The table of gamma ray sources contains a selection of historically important sources, well known sources, and extremely bright sources. The table is a subset from a catalog of gamma ray sources (Macomb and Gehrels, Astrophys. Jour. Supp., 120, 335, 1999). Bright INTEGRAL detected transients and new unidentified TeV sources were added to the table for the 2008 edition.
For the 2012 edition, bright sources detected with the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope have been included. The table is a subset from a catalog of gamma ray sources (Macomb and Gehrels, 1999; Abdo et al., 2010) along with some additions from published literature and online compilations.
The table gives two designations for each source: the most common source name in the column headed ''Designation'' and an alternate name in the column headed ''Alternate Name''. Prior to the 2012 edition, positions were mean places for the middle of the edition years. After consultation with members of the high-energy astronomy community, it was decided that J2000.0 coordinates were more useful. Therefore, beginning with the 2012 edition, the positions are with respect to equator and equinox J2000.0. The observed flux of the source is given with the upper and lower limits on the energy range (in MeV) over which it has been observed. The flux, in photons cm-2 s-1 is an integrated flux over this energy range. In many cases, no upper limit energy is given; for those cases, the flux is the peak observed flux. For SN1987A, the flux given is only for a single observed spectral line; hence the designation ''line'' is given.
The column headed ''Type'' uses a single letter code to identify the type of source as follows:
