\caption{Results of the spectral fits for the three subregions using a MeKaL model. HI column density and redshift are fixed to the average values for the whole cluster. Column 1: region analyzed. In Cols. 2 and 3 the fit parameters (temperature in keV and metal abundance, respectively) are listed. In Col. 4 is the reduced $\chi^2$ of the fit.}
