Notes. The columns contain from left to right: (1) source name; (2) X-ray flux between 0.1 and 2.4 keV; (3) high-energy flux between 1 and 100 GeV; (4) Fermi/LAT photon index; (5) status of a VHE detection; and (6) redshift status. All values come from http://www.asdc.asi.it/fermi2lac (errors not available for X-ray fluxes). The sources labelled as “Candidate” in Col. 5 are those considered to be likely to be detected in VHE in a reasonable amount of time (see text for details) Explanations about the status of the sources redshifts are given in Sect. 4.
