VERITAS Source Catalog: Gamma-Ray Observations from 2007 Onward

VERITAS, a four-telescope ground-based observatory, collects about 1100 hours of good-weather data per year. This catalog lists sources observed as of April 2022, including cross-matches with other gamma-ray observations and spectral fits. The database table was ingested by NASA's HEASARC in December 2022 and is based on data files from the VERITAS Team.

Use Cases

• Analyze spectral energy distributions of gamma-ray sources based on the spectral fits included in the catalog.
• Cross-reference gamma-ray source detections with other observatories using the provided cross-matches.
• Study the variability of active galactic nuclei based on the light curve data extracted from publications.
• Investigate source populations like supernova remnants and pulsar wind nebulae listed in the catalog.

Strengths

• Catalog is based on data from over 100 journal articles published by the VERITAS collaboration since 2008.
• Includes high-level data products and spectral fits extracted from or digitized from published papers.
• Observatory has a large collection area and high sensitivity in the 100 GeV to 10 TeV energy range.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Some data were obtained by digitizing published figures, which may introduce minor inaccuracies.
