Fitted source and background spectra for the SNR for pn (left) and MOS1/2 (right) with residuals in the energy range of 0.4–3.0 keV. The component for the SNR emission was fitted with a vpshock model. The straight lines are the modelled residual soft proton components for the corresponding detector and observation. Crosses stand for data points, while the solid lines are the fitted models. The source spectra are plotted in red (pn and MOS1) or blue (MOS2) and the background spectra in black (pn and MOS1) or green (MOS2). For better presentation, the background spectra are scaled down to the area of the SNR region, which was much smaller than the extraction region for the SEP spectrum.
