Combined count spectrum including all XMM-Newton/RGS observations, each with two diffraction orders for each of the two RGS detectors RGS1 and RGS2. For reasons of visibility, the data are binned to a minimal S/N of 3. The model consists of the underlying SXCOMP continuum complemented with a set of emission lines in blue. Line identifiers are shown on top of the individual lines.
