XMM-Newton spectral fitting of circular 10 kpc region centered at NGC 5718 with Model 1 (top), Model 2 (middle) and Model 3 (bottom). For plotting purposes only, adjacent bins are grouped until they have a significant detection at least as large as 4σ, with maximum 10 bins. Upper curve corresponds to the simultaneous fit of the XMM-Newton EPIC source and background counts, where the lower curve presents the background model.
