Top panel: simulated data and best fit model when making use of the full spectral range. The source is shown in red, the sky fore- and background in green, and the instrumental background in blue. Bottom panel: residuals in the form of a data over model ratio. All residual are below 5%, and are due to differences in the effective area and fore- and background parameters used in the simulation with respect to those adopted for the fit. We note how the low abundance value forced by the data around the Fe L-shell results in residuals around the Fe Kα line.
