Notes. The first two columns provide the common name of the galaxy and the name of the associated γ-ray source in 4FGL-DR4, d is the luminosity distance, RA and Dec are the right ascension and declination in the ICRS reference system of the center of the associated 4FGL source. Ṁ_∗ is the SFR. ℱ_2 GeV is the energy flux at 2 GeV calculated using the best-fit power-law parameters from the 4FGL-DR4.
