Left: Background-subtracted counts map of the RX J1713.7–3946 observations for the energy band 300 GeV–50 TeV. The background was estimated using the model generated by csbkgmodel with background parameters estimated using an unbinned maximum likelihood analysis using a spatial template with an exponentially cut-off power-law spectral component. Right: Background-subtracted sky map for the same data generated using ctskymap with the ring-background method for a correlation radius of 0.01°. Both maps were computed for a 0.02° ×0.02° binning and were smoothed with a Gaussian kernel of σ = 0.06° to reduce statistical noise. The colour bar represents the number of excess counts per 0.02° ×0.02° bin. Coordinates are for the epoch J2000.
