Notes. Columns N0.1 and N0.2 give the numbers of VHE photons within an angular distance of 0.1° and 0.2° from the source position. P is the chance coincidence probability for the VHE photons to be found within the 0.1° or 0.2° circles from the source. The labels “f” and “b” mark photons which are pair converted in the front and back layers of the LAT detector. Column N30−100 gives the number of photons associated with the source in the lower energy band 30−100 GeV. Emax is the maximum energy of photon associated with the source. L/LMrk 421 is the source 100−300 GeV luminosity (EBL and redshift corrected) in units of Mrk 421 (Albert et al. 2007b), computed based on the power law approximation of the source spectra, depicted in Figs. 1−16. Question marks denote the sources with uncertain redshift.
