Spectral Atlas Files for Synphot Software ("REFERENCE-ATLASES")

The REFERENCE-ATLASES HLSP presents catalogs and spectral atlases that have been prepared as inputs to the synthetic photometry software package pysynphot. These files are also used in STScI tools such as the HST Exposure Time Calculator. In addition to making the entire collection available in tar format, this HLSP provides access to individual model files for community members who may want to access only a subset of these atlases. This page provides references to the original sources, where applicable. STScI maintaines extensive documentation for these files on the Astronomical Catalogs page: http://www.stsci.edu/hst/observatory/crds/astronomical_catalogs.html
