Notes. See Fig. 10 for the best fit and the various spectral components. Column description: 1: region as defined in Fig. 8. Circle is the central circular region with radius 1.7 arcmin enclosing the regions Ring 1, 2, and 3. 2: distance from the group peak in arcmin (1 kpc at zLEDA = 0.0575 corresponds to 0.898 arsec). 3: best-fit temperature in keV. 4: metal abundance ((a) the abundance reported for region Tail 4 in the table is measured from the summed spectra of regions Tail 4 and Tail 5). 5: normalisation of the APEC model per arcmin2. The ICMEpic region is at a projected distance from the cluster centre of ~15 arcmin.
