By fitting a model made up of multiple temperature components plus a powerlaw or hot thermal component, we map the spatial distribution of the hard flux. We confirm there is a strong hard excess within the central regions. The total luminosity in the 2-10 keV band inside 3 arcmin radius is ~5x10^43 erg s^-1. As a second project we place limits on the thermal gas content of the X-ray cavities in the cluster core.
