First and second rows: EPIC/pn spectra for the regions defined in Fig. 5 (the fits were performed jointly on all 3 EPIC instruments, however only pn is shown here for clarity). The solid lines show the various components used for the fitting procedure: the source (red), the NXB (blue), the CXB (green), the Galactic halo emission (magenta), and the local hot bubble (cyan). Bottom right: EPIC/pn spectrum of the local ICM in the region close to the tip of the infalling group. The color code is the same as above.
