TEVCAT - TeV Gamma-Ray Source Catalog
This HEASARC database table provides the TeVCat list of VHE sources as well as links to the TeV source resource pages on the TeVCat website. The catalog and the website at the University of Chicago are maintained by Scott Wakely and Deirdre Horan.
TeVCat: An online catalog for Very High Energy Gamma-Ray Astronomy. Wakely, S.P., Horan, D. <Proceedings of the 30th International Cosmic Ray Conference. July 3 - 11, 2007, Merida, Yucatan, Mexico.

A sequentially assigned number for each source in the catalog. While the values are unique, they are not guaranteed to be persistent across updates.
The originating sample from which the TeV source was taken, where 1 refers to "Well-Established" sources which comprise the "default" catalog, while 2 to "Newly Announced" sources. Sources which have been published in refereed journals since the definitive detection of the Crab in 1989 are in the default catalog. Sources which have been shown at conferences or claimed in ATELs, etc., the authors place in the "Newly Announced" category, with the understanding that once the refereed publication comes out, it moves into the "default" catalog. These sources should all satisfy the traditional 5-sigma detection threshold.
A commonly used name for the TeV source.
An alternative designation for the TeV source.
The Right Ascension of the TeV source in the selected equinox.
The Declination of the TeV source in the selected equinox.
The Galactic Longitude of the TeV source.
The Galactic Latitude of the TeV source.
The type/classification of the TeV source. Most of these types are self-explanatory. The following acronyms are used:
Acronym Meaning FR I Fanaroff-Riley Type I radio galaxy FSRQ Flat-spectrum radio quasar HBL High-frequency peaked blazar IBL Intermediate-frequency peaked blazar PSR Pulsar PWN Pulsar wind nebula SNR Supernova remnant UNID Unidentified source
The flux of the TeV source, in Crab units, in the E > 50 GeV range.
The spectral index of the TeV source in the E > 50 GeV range.
The estimated distance D to the TeV source, in kpc. This is given for sources in the nearby universe (D <~ 4 Mpc). For more distant objects, the redshift is specified instead.
The redshift z of the TeV source. This is given for distant sources (D >> 4 Mpc). For nearer objects, the distance is specified instead.
The date of the TeV source discovery (YYYY-MM).
A Boolean flag parameter  which is set to 1 to indicate an extended TeV source.
The angular size of the TeV source in the Right Ascension direction, in degrees.
The angular size of the TeV source in the Declination direction, in degrees.
The URL for the TeVCat source information web page on the University of Chicago TeVCat website.
