Overview
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.
Description of Data Products
This HLSP presents a wide range of catalogs and spectral atlases, generally stored in FITS tables, as well as a handful of ASCII readme files for the individual sub-collections. Please navigate to the documentation links for detailed information about each individual atlas or catalog. Generally, data provenance is available in the primary FITS HDU headers. In addition, individual models are collected into one or more TAR files for easier access to all or large chunks of the REFERENCE-ATLASES data.
Data Access
The REFERENCE-ATLASES files are available for download both individually and as collections stored across one or more tar files, as described in the tables below.
Last Two Updates
Update 2022-04-25: The synphot throughput files for all COS FUV and NUV cenwaves - except from the unsupported NUV grating G285M - were updated based on an updated flux calibration, in preparation for ETC 30.2
Update 2021-11-23: New ACS, COS, and STIS throughput tables delivered to support ETC 30.1
Previous Update History (Expand Below)
Update 2021-10-18: The COS FUV Throughput files for G130M cenwaves 1291, 1300, 1309, 1318, 1327 and G140L cenwave 800 have been updated to be at LP5 and LP3, respectively, for Cycle 29. These changes are contained in the "synphot1" tar file below.
Update 2021-07-26: New synphot reference files in the "synphot1" tar file below (WFIRST entries were removed and replaced with Roman Space Telescope Phase C specifications).
Update 2021-06-03: New synphot reference files in the "synphot1" tar file below (new COS throughput files).
Update 2021-05-27: New synphot reference files in the "synphot5" tar file and PHOENIX individual files. The models within the phoenixm00/ directory have been updated to include more data points, and fix other issues discovered with the files.
Update 2021-05-10: New synphot reference files in the "synphot1" tar file below.
Update 2021-03-26: New CALSPEC files have been incorporated into the HLSP, available in the tar files and the directories linked below. Also, new models for JWST ETC are provided (although they also cover HST wavelengths) in the "synphot7" tar file below, and the JWST ETC Template Spectra section in the Individual Models table.
Update 2020-04-28: New CALSPEC files have been incorporated into the HLSP, available in the tar files and the directories linked below.
Update 2019-11-22: A new set of galaxy models has been added, available in the tar files and the directories linked below. These models are provided by Brown et al. (2014), and are made available here formatted for software ingest. These models are also available in original format from the GALSEDATLAS HLSP.
Update 2019-09-09: New CALSPEC files have been incorporated into the HLSP, available in the tar files and the directories linked below.
