4FGL DR4 source map for our ROI. the contours illustrate the Galactic plane emission at the 97th, 99th, 99.7th, and 99.9th percentile based on the gll_iem_v07 template. The magenta circle indicates the region where the normalization parameter were set free to compute the fit model of the ROI. In addition, Galactic diffuse emission and isotropic emission were also set to free.
