XMM and HXD spectra of A2163 in the 0.3–60 keV band fitted by a) the APEC model and b) the APEC and power-law model. The EMOS1/EMOS2/EPN data are shown by the black/red/green crosses; the blue crosses denote HXD data. Solid lines indicate the best-fit models for each instrument. In panel b), the power-law component is also indicated by the dotted line.
