2024-04-02 roman_0057.pmap archived The Roman WFI flat rmap is being updated such that each flat reference file applies to all imaging filters, rather than just F158.
2024-02-07 roman_0056.pmap archived New dark reference file for WFI spectral GRISM mode for romancal testing of 16 resultant data
2024-02-06 roman_0055.pmap archived This is a new 16 resultant dark reference file to support Build 13 using a new read pattern for testing purposes. Updating read noise reference file for development of romancal and updating flagged inverse linearity reference files from DCL data.
2024-01-31 roman_0053.pmap archived Updating the read noise reference file to a higher value to support Build 13 testing or romancal.
2023-11-09 roman_0052.pmap archived Replacing old dark files with new data model that has dark slope and dark slope variance attributes. New dark files have a new MA Table read out pattern. The linearity files were updated to have common flagged pixels, and the read noise files were generated with simulated data.
2023-07-31 roman_0051.pmap archived These are new inverse linearity reference files made from DCL data that were also used to update the linearity reference files, and are for use by romanisim.
2023-07-21 roman_0050.pmap archived These reference pixel reference files have the updated dimensions necessary for algorithm development and testing and are replacing the old files previously submitted.
2023-07-14 roman_0049.pmap archived These are new reference pixel reference files with all zeros for DMS testing of romancal functionality.
2023-06-13 roman_0048.pmap archived Replacing dark reference files to handle schema changes in Roman Attribute Dictionary and Roman Data Models handling astropy units. Theseare for DMS stress testing with different MA Table information - name, number of resultants and id number are for test only.
2023-05-25 roman_0047.pmap archived Updating all dark regression test reference files to reflect new schema changes in Roman Attribute Dictionary and Roman Data Models and the handling of astropy units. Updating all regression test reference files to reflect new schema changes in Roman Attribute Dictionary and Roman Data Models and the handling of astropy units. New linearity reference filesare also included in this submission.
2023-05-15 roman_0045.pmap archived Changed optical element name in distortion reference files from W146 to F146 to be in line with naming of the WFI optical elements.
2023-05-12 roman_0044.pmap archived Distortion files contain wrong filter name W146. New files will be submitted with correct filter name that will not crash the pipeline.
2023-04-21 roman_0043.pmap archived Delivering new IPC inter pixel capacitance WFI reference files for build 10 and usage by romanism and romancal.
2023-04-13 roman_0042.pmap archived Initial empty rmaps for wfi Inverse Linearity, IPC and refpix reference types.
2023-02-08 roman_0041.pmap archived Created a new dark reference file with 16 resultants for DMS stress testing. The ma table number id is 108 which was not previously used but similar in nature to the other dark reference files using ma table number ids 100-107.
2023-02-01 roman_0040.pmap archived Submitting new reference files to incorporate handling of units now required in updates to roman data models. WFI darks, readnoise, linearity, saturation, and gain files for both imaging and spectral modes are affected. The data arrays in dark, readnoise, saturation and gain are now quantity objects where the array of values and the unit exist. The linearity reference file only had updates to include units in the meta information, where the data remained unchanged.
2022-08-23 roman_0039.pmap archived Updates to the Roman WFI flat, distortion, dark, and linearity rmaps to correct badly formatted USEAFTER dates, where the T date-time separator has been removed and replaced with the correct, blank separator. This will now allow CRDS to replace obsolete files because it sees the T dates as distinct from the non-T dates.
2022-08-10 roman_0038.pmap archived The mission has formally set the optical element name of F146, which had formerly been named W146. To match the new schemas, the name of the optical element has been updated in the photom file for the flux conversion factor matching this element. These files also contain an updated tagged object for the telescope name in the metadata rather than a string.
2022-07-28 roman_0037.pmap archived Delivery of dark reference files to support testing of Roman DMS scaling with larger numbers of resultants per integration. This delivery supports integrations with 7 through 12 and 20 resultants.
2022-06-13 roman_0036.pmap archived Initial delivery of the Roman WFI distortion rmap, plus the initial delivery of the distortion reference files. These files are used during population of the gwcs object in the metadata during the assign WCS step in romancal.
2022-06-08 roman_0034.pmap archived Update to the Roman flat field rmap where optical elements GRISM, PRISM, and DARK have been set to return N/A as the reference file - the flat field step will be skipped for these optical elements. For the grism and prism, this is because the romancal flat step should not be applied to WFI spectroscopic mode, WSM, observations - SSC will handle this in their pipeline. The flat step code has also been updated to issue a warning and skip the step for WSM data. It is not expected that flat reference files will be delivered for the DARK optical element.
2022-06-03 roman_0033.pmap archived Removing dark and flat files that were not automatically replaced due to a change in the way the USEAFTER date is serialized in the ASDF files.
2022-05-10 roman_0032.pmap archived Submitting updated WFI dark reference files that have new meta data about the ma table number and name and match the updated xml file in place on PRD. Both the dark and flat reference files now have non zero error array values. Linearity file updates include the usage of NaNs in indices 0 and 1 to correspond to flagged pixels.
2022-05-03 roman_0031.pmap archived Updated ROMAN.META.OBSERVATION.DATE, ROMAN.META.OBSERVATION.TIME to ROMAN.META.EXPOSURE.START_TIME in all reference file rmaps. Also updated the WFI dark rmap, changing ROMAN.META.OBSERVATION.MA_TABLE_NAME to ROMAN.META.EXPOSURE.MA_TABLE_NUMBER, and setting High Latitude Imaging Survey to 1, and High Latitude Spec. Survey to 2.
2022-03-01 roman_0030.pmap archived Roman wfi flat files were deleted from the rules because they had the wrong dimensions. CRDS-538
2022-02-24 roman_0028.pmap archived The WFI flat reference file types are now 4088x4088 with the 4 reference pixel border removed. WFI dark reference files were updated to include new meta data containing MA table details. New keywords in exposure include ngroups nframes and groupgap. Both dark and readnoise reference file types had meta data updates to include p keyword options to handle both imaging and spectral modes without manually updating rmaps for imaging mode p exptype WFI IMAGE and for spectral modes p exptype WFI GRISM OR WFI PRISM. The old dark references were then deleted from the rmap because they were not replaced appropriately in the initial delivery.
2021-12-01 roman_0023.pmap archived Updating dark and readnoise rmaps to add WFI_PRISM to WFI_GRISM entries.
2021-12-01 roman_0022.pmap archived Updates to Roman reference files in support of Build 0.4, including pixel flagging for various file types incorporated. To support WFI IMAGE and WFI SPECTRAL modes the readnoise and dark files will require updates to the rmaps from WFI GRISM with WFI GRISM or WFI PRISM after delivery. Once the rmaps are updated back to the barred OR statements, the context can be update to the new pmaps.
2021-11-29 roman_0020.pmap archived Updating saturation limit per pixel from dummy values of 1 to more reasonable dummy values of 55,000 to facilitate processing of test science files in build 0.4.
2021-11-15 roman_0019.pmap archived Updated WFI dark reference file rmap to add the exposure type, WFI_PRISM, to WFI_GRISM entries.
2021-11-10 roman_0017.pmap archived Updated WFI readnoise reference file rmap to include the exposure type, WFI_PRISM, in entries with WFI_GRISM
2021-11-05 roman_0015.pmap archived Uploading reference files for Build 0.3 flat, gain, mask, and readnoise types with updated meta matching criteria and new Build 0.4 dark, linearity, and saturation file types, updated with common USEAFTER date. context roman_0014.pmap is being skipped because the reference files associated with it have inconsistent USEAFTER dates.
2021-11-01 roman_0013.pmap archived Initial rmaps for dark and saturation reference files, updated rmap for readnoise reference type, updated definitions for Build 0.4
