A TS map above 10 GeV obtained after removing the SNR and the sources 4FGL J2309.0 + 5425 and 4FGL J2303.9 + 5554 from the model (thus causing them to appear in the map). The large circle indicates the gamma-ray disk model for the SNR (whose optical contours are shown) and the squares are the catalogued positions of the 4FGL sources. The upper-left circle indicates the 68%-containment region of the LAT point spread function for both front- and back-converted events at 10 GeV.
