Context History (more history, all contexts, build contexts)

Start Date Context Status Description
2024-10-02 roman_0012.pmap latest 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.
