\caption{Results of spectral fits on the two clusters for the three different cameras. 
PNS means that only single events (PATTERN==0) are considered.
In the upper half  we show the results obtained using
the effective area files, while in the bottom half the results obtained performing
the vignetting correction directly on the events.{\label{tabfit}}}

$^{a}$ The normalizations are quoted in units of $10^{-14}~n_{\rm e}~n_{\rm p}V/4 \pi D_{\rm A}(1+z)^{2}$ as done in~XSPEC.
