Chandra spectral fitting of Sector 1 (upper) and Sector 2 (lower) with phabs × apec models. For plotting purposes only, adjacent bins are combined until they have a significant detection at least as large as 5σ, with maximum 10 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 in each panel.
