X-ray spectra from various regions of SNR G15.9+0.2, with pn and MOS2 data from the 2008 observation in black and red, respectively. All background components are included in the dashed lines (model from Fig. 3, plus straylight contamination, see Sect. 3.2). The best-fit fiducial model for the SNR emission is in green, with corresponding residuals in the bottom panels. We note the changing vertical scale between rows.
