Caption: Figure 9.
Upper panel: X-ray energy spectrum of the southeastern region of G78.2+2.1 as observed by MOS1/2 (cf. Figure 1), which is simultaneously fitted to an absorbed non-equilibrium ionization plasma model. Additional PL components have been applied to account for the residual soft proton contamination in the individual camera. Lower panel: contributions to the χ2 fit statistic.
