\caption{Best fit parameters for the power-law model using the MOS and pn data all at once.
The errors are in the range $\Delta \chi^2 < 2.7$ (90\% confidence level) on one parameter.
The regions shown in Fig. \ref{hardness_ratio}.
$Norm$ is given in units of photons/cm$^2$/s/keV/arcmin$^2$ at 1~keV.\label{mo_wapo_mp}}
