Figure 2.
The photon index (|$\Gamma$|) versus the integral flux in the 10–800 GeV energy band. The green points represent 1CGH sources with counterparts in both 3FHL and 4FGL-DR4 catalogues; the blue open diamonds represent 1CGH sources with counterparts in 4FGL-DR4 only; and the magenta circles represent new |$\gamma$|-ray identifications.
