This MIRI IFULONG linearity file is an update for the band NA file currently in the pipeline, meant to be used for flight data. It only applies to IFULONG dark files, and is an exact copy of the MIRIFULONG MEDIUM file, with changes to the header keyword. |

A delivery of NIRCam bad pixel mask reference files, which contain updates to the bad pixel population discovered in the long dark current ramps taken as part of JWST commissioning. These updates come from analysis of the long dark current exposures taken early in commissioning.
A delivery which updates the MIRI IFULONG linearity files to improve on the previous versions of these files for flight, as well as providing a linearity file for the F2550W Imager flight data.
A delivery of NIRCam longwave channel, full frame dark current reference files, which contain the mean dark current signal as measured during commissioning. This represents a better measure of the dark current compared to the previous reference files, which were constructed using ground testing data. |

There was an update to the NIRCam pars_whitelightstep reference file rmap to add an entry for TSIMAGE and set it to N/A - the step is not needed for this type of data. Plus, a new NIRISS linearity reference file. The previous version of the file contained about 6000 pixels that were flagged as NO_LIN_CORR because the linearity fitting failed, even though they had reasonably normal linearity properties as far as can be seen from the input ramps used to determine the coefficients. Excluding a couple of areas where there are detector defects, these pixels in the file that was delivered have had the mean linearity coefficients used and the NO_LIN_CORR flag removed. |
