4FGL J1349.5−6206c and src Fermi-LAT SED in the 0.1–100 GeV energy range. Black dots correspond to the Fermi-LAT spectrum of the 4FGL J1349.5−6206c γ-ray source. Red dots represent the Fermi-LAT spectrum of the src (spatially coincident source to the SNR G309.8+00.0) γ-ray source. As expected from the obtained TS maps of Fig. 5, the γ-ray emission of the 4FGL J1349.5−6206c γ-ray source is dominated by the src component at higher energies.
