Start Date Context Status Description
2025-01-04 roman_0018.pmap latest Roman WFI absolute photometric calibration information was used to generate new photom files with throughput information coming from the Roman Technical Information Repository. These files are needed for the upcoming Roman science platform tutorial and development and testing before AAS.
2024-12-28 roman_0017.pmap archived The inverse linearity reference files were derived as a first pass attempt of using TVAC2 data to make more realistic products for use with Roman Science Platform testing and tutorials at the upcoming AAS conference.
2024-12-24 roman_0016.pmap archived These files are copied from Roman Test CRDS and have had their meta data updated to reflect their origin. They are needed to support Roman Science Platform testing and tutorials at the upcoming AAS.
2024-12-23 roman_0015.pmap archived These files are copies of the distortion files from test roman crds but have had the author and description updated to state as much.
2024-12-19 roman_0014.pmap archived These dark files represent all of the matching science Multi Accumulation Table information that currently exists in PRD. Specifically, MA Tables 3 through 17 and excluding defocus and diagnostic MA Tables 1,2 and 18. These files are intended for use in creating and processing data from L0 to L2. The values of the data are all zero and the files were compressed with internal asdf functionality.
2024-12-19 roman_0013.pmap archived These are the first pass of flat files for optical elements F087 and F129 from TVAC 2 data utilizing bands 1 and 3. These are intended as first attempts to have realistic CRDS data for Roman Science Platform testing and tutorials on the TVAC server.
2024-10-02 roman_0012.pmap archived These are first pass gain reference files derived from TVAC1 data. They use an algorithm developed by Tim Brandt and every pixel is ensured to have a determined value or a filler value of 1.8.
2024-10-01 roman_0011.pmap archived These are the first versions of linearity and saturation reference files derived from TVAC 1 data and are intended to be sufficiently accurate enough as place holders until more refined measurements of future updated files.
2024-09-10 roman_0010.pmap archived New mask reference files incorporating optical bad pixel maps from GSFC are being updated and made available.
2024-08-27 roman_0009.pmap archived Uploading a reference pixel reference file that was not delivered with the initial batch of files.
2024-08-09 roman_0008.pmap archived Initial empty rmaps for area, distortion, flat, gain, inverselinearity, ipc, linearity, photom, readnoise, and saturation.
2024-08-02 roman_0007.pmap archived Roman TVAC was using an incorrect parkey in the mappings. We are delivering a new pmap with the corrected parkey, ROMAN.META.INSTRUMENT.NAME, to fix this.
2024-06-25 roman_0006.pmap archived Initial TVAC bad pixel map Mask reference files to be used during the DQInit step of romancal for processing TVAC data after converted to asdf format.
2024-06-11 roman_0005.pmap archived Initial empty rmap for mask reference files
2024-05-10 roman_0004.pmap archived These are reference pixel reference files made from TVAC1 data from the total noise test. This submission is the first to the TVAC server and these files are essential for removing 1 over f noise in Roman data.
2024-04-11 roman_0003.pmap archived Initial empty rmaps for wfi dark and refpix
2024-01-30 roman_0002.pmap archived Insert rule for WFI
2024-01-30 roman_0001.pmap archived Initial pmap for ROMAN TVAC server.
