Calibration Reference Data System, HST/JWST reference file management

Project description


CRDS is a package used for working with astronomical reference files for the
HST and JWST telescopes. CRDS is useful for performing various operations on
reference files or reference file assignment rules. CRDS is used to assign,
check, and compare reference files and rules, and also to predict those
datasets which should potentially be reprocessed due to changes in reference
files or assignment rules. CRDS has versioned rules which define the
assignment of references for each type and instrument configuration. CRDS has
web sites corresponding to each project ( or which record information about reference files
and provide related services.

Releases are `registered on PyPI <>`_,
and development is occuring at the
`project's github page <>`_.
