Vega STIS spectrum relative to models
Ratio to the 9550 K model continuum level for the STIS measured fluxes (black), the Kurucz 9550 K, log g=3.95 model (green), and the Kurucz 9400 K model (red). The models and the 9550 K continuum level are all normalized at 5557.5 Å (vacuum) to 3.44 ⅹ 10-9 erg cm-2 s-1 Å-1.

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.

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.
