Reference Files Naming ConventionΒΆ

Before the reference files are ingested into CRDS, they are renamed following a convention used by the pipeline. As any other changes undergone by the reference files the information of the previous names is kept in the keader keywords, so the Instrument Teams can easily track which delivered file is being used by the pipeline on each step.

The HISTORY header keyword of each reference file includes details on specific processing undergone by the files before being ingested in CRDS.

The reference files names used by the different pipeline steps are define in the table below. Details on the files formats used and the CRDS selection criteria are given in the correspondent pipeline sections defined in this document.
