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

Start Date Context Status Description
2024-10-30 roman_0065.pmap latest Removing the parameter file roman_wfi_pars-jumpstep_0001.asdf for Jump Step on because this file was delivered as a dummy and is now obsolete.
2024-10-17 roman_0064.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.
2024-08-07 roman_0063.pmap archived Testing the online retrieval of parameters files.
2024-08-07 roman_0062.pmap archived Delivering a new Roman WFI pars-jumpstep rmap for the github CRDS issue 1053 - Adding Pattern Translations for Roman Parameter Files
