Notes. The time period MET 542144904 − 550885992 was excluded due to the bright nova ASASSN-18fv, or V906 Carinae, (Aydi et al. 2020) within the ROI.

Even though disabling the energy dispersion for the galactic diffuse component is not the standard procedure with a model based on the 4FGL catalogue, this does not significantly affect the result due to the high energy threshold of the analysis.
