Hammer–Aitoff projection in Galactic coordinates of 2FLE detected sources. Supernova remnants (SNRs) and pulsar wind nebulae (PWNe) are indicated with a green cross, pulsars (PSRs) with a cyan cross, BL Lacertae objects (BL Lacs, BLLs) with a blue star, flat-spectrum radio quasars (FSRQs) with a red diamond, blazars of undetermined type (BCUs) with a yellow square, while all other extragalactic associations (Other EGAL) are indicated with a green triangle, all other Galactic source types (Other GAL) with a pink triangle, and unassociated sources (Unassoc) with a gray circle. This map showcases the dominance of FSRQs out of the source types detected in the MeV population, as well as preponderance of sources detected at ∣b∣ > 10° in the 2FLE.
