\caption {\label{fxfgbands}Values of the slope $\beta$ of the correlation $F_{\gamma}\propto F_x^{\beta}$,
for fluxes integrated over different energy bands, as indicated.
The 3--15~keV flux is obtained by extrapolation of the  power-law model in the \chandra~ passband.  
Fit of the dataset ``B+C'' in the 7--14~min binning. }
