Start Date Context Status Description
2020-10-09 jwst_0642.pmap operational The new NIRISS gain reference file was created using new Python scripts adapted from an IDL version of the same algorithm. This file is described in technical report JWST-STScI-005661. It was made using the same set of CV3 darks as the previous version of this file. IPC corrections differ slightly from the previous version due to newly calculated smaller corrections resulting in more pronounced epoxy void regions. Gaussian smoothing is applied after patching and IPC correction to remove edges between the 20x20 px tiles over which the gain is calculated. The mean gain over the illuminated region of the detector is 1.6221 plusminus 0.036, compared to the previous mean of 1.6246 plusminus 0.046 electrons per DN. The smoothing does not change either the overall mean or the four channel means by a significant amount.
2020-09-11 jwst_0641.pmap archived As indicated in the referenced JIRA issues, an error occurred during SOC 2.1 validation testing due to missing SUPERBIAS and DARK reference files for NRS1, SUB2048, and DISPERSER set to MIRROR. These dummy files were created to fill this gap in coverage. Reference files with real data will be submitted when such data becomes available.
2020-09-08 jwst_0640.pmap archived Initial delivery of the NIRISS pars-image2pipeline reference file. See JIRA issues CRDS-364, CCD-688, and JP-1246 for more details.
2020-08-28 jwst_0637.pmap archived Activate updates for NIRSpec dark current and default cube build parameters.
2020-08-12 jwst_0635.pmap archived Activate NIRISS flat reference changes and Spec2Pipeline steppars to support NIRSpec Lamp processing.
2020-07-28 jwst_0630.pmap archived New photom reference files are being delivered to CRDS for MIRI LRS slit and slitless modes. These files removed the zero padding of the data arrays and improved upon the other values in the arrays.
2020-07-17 jwst_0629.pmap archived Activate APCORR updates and NIRSpec pars-spec2pipeline initial rmap.
2020-07-07 jwst_0625.pmap archived The previous version of the JWST MIRI LRS apcorr file had a column, nelem_wl, defined as data type uint16 rather than a regular signed integer, int16 as specified in the JWST data model, which caused problems in the pipeline. This column data type has been updated in this version of the file. No science data has been changed. Further details can be found in JWSTMIRI-118.
2020-06-25 jwst_0624.pmap archived Activate APCORR rmap and reference file changes.
2020-05-28 jwst_0619.pmap archived Activate updated APCORR references.
2020-05-18 jwst_0616.pmap archived Activate new MIRI FILTEROFFSET and updates to NIRCam APCORR.
2020-05-07 jwst_0614.pmap archived Activate all new reference file types delivered for Build 7.5 including APCORR, ABVEGAOFFSET, RSCD, and NIRCam FILTEROFFSET.
2020-05-05 jwst_0592.pmap archived Update for Build 7.5 of JWST to include support for APCORR, NIRCam FILTEROFFSET, new format of MIRI RSCD, and ABVEGAOFFSET.
2020-03-04 jwst_0586.pmap archived A new FGS PHOTOM rmap delivery is necessary because exposures with EXP_TYPE=FGS_FOCUS in the current rmap are triggering an error in the calwebb_image2 pipeline when trying to run the PHOTOM step. This exposure type specification selects a very old PHOTOM reference file, jwst_fgs_photom_0011.fits, that is missing the DATAMODL keyword in its header, which confuses the pipeline and causes an error in the PHOTOM step process. Since the new FGS PHOTOM reference files get used for EXP_TYPE=FGS_IMAGE, the exposure criteria in the rmap needs to be updated to include FGS_FOCUS because focus images and regular images should receive the same processing. Also, old FGS PHOTOM reference files should be removed from the rmap because they are no longer compatible with the latest pipeline software. See JIRA issue CRDS-333 for more details.
2020-02-28 jwst_0585.pmap archived These files replace previous REFPIX files were delivered without DQ extensions. In addition, the TZERO3 keyword in the DQ extension has been changed to an integer.
2020-02-19 jwst_0584.pmap archived The MIRI LRS PHOTOM files are being updated after corrections to the analysis procedure used to create them. Specifically the implementation of slit loss factors and extraction aperture were inaccurate. This problem should now be fixed
2020-02-11 jwst_0583.pmap archived As described in the JIRA tickets listed above, a number of NIRSpec biases and darks for the SUB1024A, SUB1024B, SUB512, SUB512s, and SUB32 subarrays were either missing, or had been previously delivered with the wrong subarray corners or orientation. This delivery contains corrected files to supply or replace these. Note that many of the files are placeholders, and the data arrays have been set to 0. Future deliveries will provide actual reference file data, once it has been received by NIRSpec.
2020-01-27 jwst_0582.pmap archived This NIRCam readnoise delivery derived from CV3 data is to correct cosmic ray flagging for data without reference pixels. Data taken with subarrays that dont have reference pixels, and thus no reference pixel correction, were getting almost entirely flagged as cosmic ray hits when run through the pipeline due to our current readnoise reference files. For this reason, we created new readnoise reference files for use on all data without reference pixels. We also redeliver the old readnoise reference files from the corresponding detectors, but the only change in these old files is the addition of the P_SUBARR keyword.
2020-01-17 jwst_0581.pmap archived Removing MIRI flats with READPATT = ANY. These were meant to be replaced with files containing READPATT = N/A. See JIRA ticket CRDS-328. CRDS weighted matching logic for reference files has jwst_miri_flat_0472.fits and jwst_miri_flat_0535.fits weighted equally, causing there to be two valid files for some cases. The rmap is being updated to remove the NA from READPATT and replace it with specific values FAST, FASTGRPAVG, and SLOW using or-bars. Additionally, the READPATT value of NA for jwst_miri_flat_0473.fits is being replaced by SLOW in order to avert any future problems.
2019-12-13 jwst_0579.pmap archived Per ticket JP 834 cube build has been modified to allow for an exponential falloff to the radial weight function. This update requires a corresponding update to the reference files to provide the default parameters for the choice of an exponential profile. Pull request 4313 cannot be merged until this updated file is present in crds, as it will otherwise cause a pipeline crash. The new reference file is backwards compatible, in that it will not crash the current pipeline, just provide extra information that the current pipeline will ignore.
2019-12-11 jwst_0578.pmap archived Fixes jira ticket JWSTDMS-216. Datasets with MIRI EXP_TYPE TACONFIRM are failing in build 7.4 of the data pipeline. The rmap changes here should fix these problems. Removes the SUBPRISM subarray from the MIRI dark file jwst_miri_dark_0048.fits.
2019-12-09 jwst_0576.pmap archived CRDS and pipeline have now been updated to use the SLITLESSPRISM subarray name rather than SUBPRISM, therefore remove the SUBPRISM specific reference files.
2019-12-08 jwst_0575.pmap archived We have a list of MIRI reference files that are still valid in the current context and showing up on the jwst-crds pages. Many of these had mismatched USEAFTER dates that prevented them from being replaced with the more recent versions during deliveries of updated files. The files should be removed from the context as they are not current and have been replaced by updated files.
2019-12-06 jwst_0574.pmap archived These MIRI PHOTOM files are being redelivered after testing by J. Schreiber, MPIA Heielberg and MIRI IDT member, revealed an error in how the values in the table were derived. The spectral response values are supposed to be provided on a per pixel basis, whereas the previous version still assumed a spectral extraction aperture. In this new table, the values were divided by the number of pixels assumed in the aperture, so as to represent the spectral response conversion per pixel, which is how the calibration step is applied. There were no changes to the format of the file, or how the reference data are supposed to be applied to the science data.
2019-12-04 jwst_0573.pmap archived The NIRCam PHOTOM reference files, jwst_nircam_photom_0053.fits - jwst_nircam_photom_0061.fits and jwst_nircam_photom_0063.fits are being removed due to duplicate matching rules with EXP_TYPEs NRC_CORON, NRC_FLAT, NRC_IMAGE, NRC_TACONFIRM, NRC_TACQ, NRC_TSIMAGE for files activated on 2019-12-03
2019-12-03 jwst_0572.pmap archived Update to NIRISS PHOTOM rmap to include NIS_FOCUS due to failures seen in Level2b processing failures. See JIRA issue CRDS-322 for more information.
2019-12-03 jwst_0571.pmap archived These photom reference files replace those delivered two months ago. Their data in the tables are identical to those in the files being replaced. The only difference is the addition of NRC_FOCUS to the P_EXP_TY header keywords. This is added so that these reference files will be selected for NRC_FOCUS observations. In the previous version of these files without NRC_FOCUS in the exp_type list, the photom reference files selected for NRC_FOCUS data were dummy files with a file format that no longer matches what the pipeline expects.
2019-11-20 jwst_0570.pmap archived These are dummy NIRCAM PSFMASK files to fill in the missing modes for SUBARRAY FULL and SUB320A335R in the NIRCam F444W filter.
2019-11-14 jwst_0569.pmap archived Update to NIRCam PSFMASK rmap where obsolete MASK values MASK210R, MASK335R, MASK430R, MASKLWB, and MASKSWB were updated to MASKA210R, MASKA335R, MASKA430R, MASKALWB, and MASKASWB, respectively. See JIRA issue JWSTDMS-63 for more information.
2019-11-12 jwst_0568.pmap archived This is a redelivery of the FGS dark and superbias rmaps. The previous versions of the files had had the subarray names inadvertently changed back to their old names after validation errors occurred during a reprocessing run. This delivery restores the rmaps to what they were previous to the last delivery - the subarray names are now correct. Updated photom parameter to fix Level2a failures were seen with the following msg for some NIRISS cases in nOPS6. Update to the naming of the sub arrays in the JWST FSG dark and superbias. This should correct the bug that was found in JIRA issue CRDS-321.
2019-11-08 jwst_0565.pmap archived Removes files from the NIRSpec PHOTOM rmap that needed to be replaced with updated reference files that were delivered on October 23, 2019. Sets the updated reference file USEAFTER to 2010-01-01, correcting dates which only covered recent data. See JIRA issue CRDS-310 for more information.
2019-11-01 jwst_0563.pmap archived These new NIRCam distortion reference files were created using the astrometric solution contained in the PRD as of 24 Oct 2019. Using pysiaf version 0.6.1, the polynomial coefficients and other aspects of the distortion model were placed into these reference files. Previous coefficients, and the previous reference files that used them, were incorrect in that coordinates did not round trip from science x, y to v2, v3, and back to science x, y properly. These new files contain coefficients that correct that error. Details of this correction are documented in the JIRA tickets JWSTSIAF-161 and JWSTSIAF-123. In addition, these new files correctly reflect the possible exposure types for each astrometric solution. Target acquisition and TA confirmation images can be taken either with or without the coronagraphic wedge in the pupil, and therefore the NRC_TACQ and NRC_TACONFIRM exposure types must be included in both the imaging and coronagraphy reference files. Also included in this delivery are distortion reference files for coronagraphic observations using the module B detectors. Observers are not currently allowed to take coronagraphic observations using module B, but this may change in the future. Updated NIRCam distortion mapping to remove old files that contain incorrect astrometric solutions and should not be used.
2019-11-01 jwst_0561.pmap archived jwst_miri_flat_0245.fits has a USEAFTER of 2014, which is more recent than the USEAFTER of a newer file, which has a 2013 date, and would keep the new file from being used for any new data, and so it should be removed. See JIRA issue CRDS-268 for more information.
2019-10-29 jwst_0560.pmap archived The MIRI MRS PHOTOM files were updated to be a multiplicative correction rather than a division in order to work with build 7.4 of the photom step. These files comply with the format specified in JP-1018. This update was necessary to have reference files that worked with an update to the pipeline. The MIRI Instrument Design Team has changed their approach to creating the pixel flats, and no longer believes that the pixel flats used previously are properly representative of the actual relative responsivity of the detectors. In particular, any benefits provided by percent-level pixel-to-pixel corrections were dwarfed by about ten percent level systematics in the previous algorithm near the edges of the IFU slices. In a continuing effort to better characterize the instrument performance the flatfield and PHOTOM analysis efforts have been merged together. While analysis is ongoing the values in the pixel flats have been replaced by dummy values, 1.0, so that they do not degrade the quality of the calibrated data products using the new PHOTOM reference files. This change should produce improved performance for both ground test data and simulated data. The MIRI data simulator will soon also be adopting the updated FLAT and PHOTOM files.
2019-10-29 jwst_0559.pmap archived NIRCAM DARK Failure to process LOS Jitter data using module B revealed that the current reference files for module A, SUB8FP1A, is actually a DUMMY file that will never be replaced. This type of data is used by the WFSC team and they do not require to have DARK correction as they are going to use their own tools to analyze the data. As such, we decided that rather than adding yet another Dummy file for module B we should remove the existing one for module A and change the RMAP so the DARK correction is not applied to this type of data.
2019-10-24 jwst_0558.pmap archived Initial delivery of NIRSpec PHOTOM reference files with datamodels separated by mode. See JIRA ticket JP 1018 for specifications.
2019-10-24 jwst_0557.pmap archived This is the first delivery of separate MIRI LRS fixed slit and slitless files. The single file previously delivered was split into separate parts in order to allow different pixel area keyword values for the two modes. There are now individual files for fixed slit mode and for slitless mode
2019-10-24 jwst_0554.pmap archived New NIRISS PHOTOM reference files with EXP_TYPE as a new selection criteria - AMI, WFSS, and SOSS. Most of the values in the tables are unchanged, but for the SOSS case, the PHOTMJSR value has been changed to PHOTMJ. The values of the PHOMJ keyword are different by a factor of 1.e-09 due to a change in units from milliJansky to megaJansky.
2019-10-24 jwst_0553.pmap archived This delivery is using the new MirImgPhotomModel and MirLrsPhotomModel data models for the MIRI PHOTOM files. An update has been made to separate out the Imager modes and the LRS modes. The columns nelem, wavelength, relresponse and relresperror have been removed from the Imager file, and the column relresperror has been renamed to reluncertainty in the LRS file. The LRS file is being delivered as a separate file for the first time, and has added PIXAR_SR and PIXAR_A2 keywords to the header. The MIRI Imager file has added the EXP_TYPEs to the header MIR_IMAGE, MIR_4QPM, MIR_LYOT, MIR_TACQ, MIR_TACONFIRM, while the LRS file has the EXP_TYPEs MIR_LRS FIXEDSLIT and MIR_LRS SLITLESS. These files are being delivered to the JWST TEST server until the pipeline is updated to be able to use the new format files.
2019-10-24 jwst_0552.pmap archived The JWST pipeline will begin using EXP TYPE as a selection criteria for the photom reference files, so the EXP TYPE header keyword has been updated to reflect the exposure types that will be run through the photometric correction step. The photmjsr value in the data has also been replaced with a more updated value, although it was already multiplicative, so the old value wasnt bad, just out of date.
2019-10-24 jwst_0551.pmap archived These photom reference files are the first set of NIRCam flux calibration reference files with realistic values in them. Previous versions contained dummy data. These files also match the new file format decided upon in Sept 2019, where EXP_TYPE is included in the selection criteria. The column names are EXP_TYPE dependent. Also, the photmjsr values are multiplicative in this file. These values should be multiplied to the science data in order to convert from counts per second to MJy per sterradian. This differs from previous versions, where the data were divided by photmjsr. Synphot was used with filter throughput curves and a spectrum of Vega in order to calculate flux densities and count rates. In the WFSS files, in the few places where the throughput was exactly zero, such as in the area between the main bandpass and a red leak, the photmjsr value was set to zero. This will cause pixels seeing these wavelengths to be set to zero after the photom file is applied. The only entries in these files that still contain dummy values are those for the PINHOLES pupil element.
2019-10-24 jwst_0550.pmap archived New MIRI RESET reference files.
2019-10-24 jwst_0549.pmap archived First empty MIRI RESET .rmap
2019-10-23 jwst_0548.pmap archived Updates to FGS, MIRI, NIRCAM, NIRISS PHOTOM .rmaps to add EXP_TYPE as a matching parameter.
2019-10-09 jwst_0543.pmap archived Updated DQ array to mask out 4 quadrant phase masks as non-science for MIRI full frame imager data. All FULL Frame MIRI FLAT files in CRDS with a USEAFTER of 1900-01-01 should be deleted. These files should all have a counterpart dated 2000-01-01 and the older dated files are no longer needed to be active in the system, as they were delivered three years ago and we have newer versions delivered.
2019-07-30 jwst_0541.pmap archived As per Jira issues CRDS-287, REDCAT-52, and CRDS-153, the rmaps for the following NIRSpec reference types were updated to include READPATT values of NRSRAPIDD1, NRSRAPIDD2, and NRSRAPIDD6. This rmaps submission includes changes to the following DARK, READNOISE, REFPIX and SUPERBIAS.
2019-07-23 jwst_0540.pmap archived New MRS REGIONS files for all channel-band combinations are being delivered to fix an issue where a few slices were incorrectly a fraction of an arcsec too long. There are no header format changes, no necessary pipeline revisions, and everything has been tested to work cleanly using the current conda-dev with these new reference files. CRDS-285 adds additional NIRCam science and engineering pupil filter parings to the flat rmap for time series. Missing coverage was revealed from a DMS processing run of SOR4B Time Series grism data.
2019-07-10 jwst_0538.pmap archived As per JIRA ticket CRDS286, JP-830 and JWSTDMS-32 reported a failure of CRDS when selecting reference files for the MIRI Target Acq exposures, during calwebb_spec3 processing. This map submission is to define EXTRACT1D=N/A for MIR_TACQ cases.
2019-07-08 jwst_0537.pmap archived MIRI SUPERBIAS and DARK files created using data from OTIS testing in advance of the CDP4 delivery, for GSEG3 testing. The files have 88 frames, which provides more than enough data to be frame averaged for NRS data, as per JIRA issue CRDS 282. NIRSpec area rmap where NRS_MSATA and NRS_WATA were added to the list of EXP_TYPEs that do not need this type of reference file applied. See JIRA CRDS-284 for more information.
2019-06-24 jwst_0535.pmap archived Per CRDS 220, initial delivery of NIRCam coronagrphic flats based on CV3 imaging flats.
2019-06-12 jwst_0534.pmap archived Addressing Jira CRDS-279 and CRDS-280, adds EXP_TYPE as a matching parameter to MIRI and NIRCAM PSFMASK and NIRCAM DARK so that TACQ exposure modes respond with N/A.
2019-06-04 jwst_0532.pmap archived As per JIRA ticket CRDS277, this map submission is to support the SLITLESSPRISM subarray which will replace the SUBPRISM subarray in the future. In addition, FASTGRPAVG readout pattern support was added to both subarrays.
2019-05-31 jwst_0531.pmap archived The NIRCam science team has requested that two new filters be offered in combination with the 8-wave weak lens in the NIRCam Grism Time Series template. This update was to the NIRCam flat reference rmap to include the WL8 in combination with F070W and F140M flat reference files. See CRDS 274 for further details. New delivery of updated files from the MIRI IDT. Distortion file has improvements in spatial and spectral dimensions, fixes a trace curvature issue in previous files, convert directly to V2,V3 rather than XAN, YAN, and has an update to the slice mask file format. Instead of being 2d images for each detector, file is now 3d array of images with different throughput thresholds. Delivered by Misty Cracraft for MIRI. As per JIRA ticket JP667, these reference files were created from data taken during OTIS testing, and received in advance of the full CDP4 delivery. The files with a subarray keyword of GENERIC have subarray corner values which were updated between CV3 and OTIS testing, and now match those used by OSS. MIRI LRS PHOTOM modes have a new column called relresperror which gives the response error. The column is available for all rows, but only has valid data for rows 15 and 16, the LRS modes. Updates for CDP7 for MIRI single dichroic files, slice mask of 10 percent transmission added, cdp7 Fringe flat applied, and addition of new cross dichroic files. Support CALVER 0.13 for SYSTEM VERSIONS web service. This NIRCam delivery is to provide flat coverage for F070W and F090W. CV3 F115W flat data is used for these reference files since ground data from F070W and F090W shows low S/N and the presence of structure possibly due to the illumination source.

2019-04-23 jwst_0504.pmap archived NIRCAM FLAT - Currently in CRDS, there exists a set of flat field reference files that have FILTER and PUPIL keyword values of ANY. These were delivered to CRDS by the pipeline developers during the initial development phase of the pipeline and contain dummy data. These files should be removed from CRDS or flagged in such a way that they are never selected. Currently they are selected in cases where a valid flat is not found. NIRISS MASK, PHOTOM - An error in the SOSS mode photometric calibration has been corrected in the new version delvered here. An error in the bad pixel mask has been corrected in the new version delivered here. Delivered by Kevin Volk for NIRISS.

2018-08-01 jwst_0478.pmap archived SCSB has defined a new DQ flag condition REFERENCE PIXEL, which needs to be added to the reference pixel locations in the MASK reference files for all instruments and detectors. The new files are the same as the old versions except that reference pixels are now flagged with the new REFERENCE PIXEL value and the DQ DEF table includes the new REFERENCE PIXEL flag. Delivered by Graham Kanarek for NIRSPEC.
2018-07-23 jwst_0477.pmap archived The current version of NIRISS subarray DARK and SUPERBIAS have the PREADPA NIS NISRAPID Readout pattern header keyword, various symbols are missing from the header keyword, but was added outside of the pipeline that creates the dark and bias reference files originally. These files have been created from the darks and biases pipeline.
2018-07-18 jwst_0476.pmap archived Corrected DQ array orientation for NIRISS FLAT references. Added MIRI and NIRCAM TSOPHOT rmaps and references for Jira CCD-119, all other instruments are N/A.
2018-07-12 jwst_0471.pmap archived Replaced NIRISS FLATs for new data models and updated DQ handling. Replaced NIRISS DARK and SUPERBIAS files for revised DQ handling. Replaced FGS MASK files for revised definitions of bad pixels.

Updated NIRSPEC gain rmap to add jwst_nirspec_gain_0019.fits and jwst_nirspec_gain_0018.fits for NETA.SUBARRAY.NAME equal to GENERIC for the NRS1 and NRS2 detectors, respectively, so that they will apply to all subarray data taken before April 1 2017 where the gain was 1. For subarray data taken after April 1 2017 where the gain is set to 2, jwst_nirspec_gain_0017.fits for NRS1 and jwst_nirspec_gain_0016.fits for NRS2 will be used, as discussed in Jira CRDS-216. Also dropped obsolete 3D MIRI DARK files which no longer run with CAL, as discussed in Jira CRDS-206.
2018-06-01 jwst_0465.pmap archived New NIRSPEC OTE and IFUPOST rmaps where the USEAFTERs for the newest files, jwst_nirspec_ifupost_0004.asdf and jwst_nirspec_ote_0005.asdf, were changed to 2015 11 01 in order for CV3 data to be fully covered by the new files.
