Data Affected: All NIRCam data
These new superbias reference files cover all detectors and subarrays. The updated files were created from cycle 2, 3, and 4 data, with the exact date range depending on the subarray and the schedule of past dark current observations. The superbias data contained within these files were created using the 0th frames of dark current integrations. No reference pixel correction or other pipeline steps were applied to the input data. These files differ from those delivered in March 2026 only in that the previous files contained erroneous values of 1 in their data quality arrays for pixels with unreliable bias values. This led to those pixels having a value of NaN in the rate and cal files. In past superbias reference files, these pixels are instead flagged with the UNRELIABLE_BIAS flag, and ramp-fitting is allowed to calculate slope values for them. These new superbias files return to that strategy. |

Affected data -- NIRCam coronagraphic F070W, F090W, F115W, and F150W modes, DHS and weak lens, psfmask and filteroffset reference files.
These new psfmask reference files are the initial files to support pipeline processing for the bluest NIRCam filters when used for coronagraphic observations. These are copies of the existing psfmask reference files for the F210M filter, which have not had any filter-dependent shift added. These files will be updated once commissioning data are used to determine the filter-dependent shifts.
These updated NIRCam filteroffset reference files are identical to the previous versions with one exception. The names of the DHS and weak lens pupil elements have been corrected. In the previous version of the files, the DHS pupil names were e.g. DHS0 through DHS11. These have been corrected to GDHS0. Similar corrections were made for the weak lenses WLP8 and WLM8, as well as GDHS60. With these corrections, the pipeline will be able to locate the correct row for a given observation. In the previous version of the files, the pipeline failed to find a matching row, noted that in the log, and moved on without adding a filter-based offset. However, since all of the DHS and pupil wheel-based weak lens rows contain zeros for the filter-based offsets, there will be no practical difference in NIRCam data when these new reference files are used. |

Affected data: NIRCam coronagraphic observations using F070W, F090W, F115W, and F150W are affected
New entries have been added to the current NIRCam photom files to support the use of the four filters mentioned above in coronagraphic observations, with the MASKRND and MASKBAR pupil wheel elements. The flux calibration values in these files have been set to 1.0 at the moment, and have been put in place to support pipeline processing of the initial calibration observations for these new filters. The values will be updated with real values once flux calibration data for these new filters have been analyzed. No flux calibration information for any other filter-pupil combination has been changed. |

Affected Data: NIRSpec MOS and IFU observing modes. There is a new failed open shutter in Q2. This delivery also reflects the change in the failed closed/open shutter populations.
Also delivering a new NIRCam distortion rmap with FILTER values updated for reference files 0317, 0318, 0319, 0320, 0322, 0323, 0324, and 0326. These files will be used to calibrate data using the bluest filters in the SW channel - F070W, F090W, F115W, F150W, F182M, F187N, F200W, F210M, and F212N. This will enable support for the upcoming calibration proposal where these new filters will be used in coronagraphic observations. |
