Description

VTSCat is the catalog of high-level data products from all publications of the VERITAS collaboration.

Release version v4.0.0 includes all VERITAS publications through early 2026.

The VTSCat data collection contains:

  • high-level data like spectral flux points, light curves, and spectral fits in human- and machine-readable YAML and ECSV formats
  • tabulated data like upper-limits tables from dark matter searches or results on the extragalactic background light in ECSV format
  • sky maps (wherever available) in FITS format

A detailed description of VTSCat can be found in A. Acharyya et al 2023 Res. Notes AAS 7 6. Please also see the README file and all documentation linked to the README.

VTSCat supplements the HEASARC catalogue of VERITAS results, accessible through this link. VTSCat is inspired and derived from gamma-cat.

If you are a former VERITAS collaborator and and would like to be associated with this repository, please send an email to G. Maier.
