Spatial and spectral characterization of the γ-ray emission results of left panel: zoomed-in view of the Fermi-LAT TS map at the Kepler SNR position above 1 GeV. The green contours are from the infrared 24 μm Spitzer map. The plus symbol and circles illustrate the best-fit position and the 68 and 95% confidence contours. Middle panel: Fermi-LAT TS map of the 15° × 15° ROI around the Kepler SNR above 100 MeV. Magenta plus symbols represent the sources from the 4FGL-DR2 catalog and the green symbols the added point sources. For both TS maps, the Kepler SNR was not included in the model. Right panel: SED of the Kepler SNR obtained using the infrared spatial template. Blue error bars represent the statistical uncertainties, and the red ones correspond to the statistical and systematic uncertainties added in quadrature.
