Chandra spectral fitting of r = 3 kpc circular region centered at NGC 5718 with Model 1 (upper) and Model 2 (lower). For plotting purposes only, adjacent bins are combined until they have a significant detection at least as large as 2σ, with maximum 5 bins. Upper curve corresponds to the simultaneous fit of the Chandra ACIS-I source and background counts, where the lower curve presents the background model.
