  $^a$ Percentage of the soft (hard) X-ray luminosity 
associated with the power-law component. $^b$ Eddington ratio $L_{\rm bol}/L_{\rm Edd}$,
where $L_{\rm bol}$ was
obtained by multiplying the 2--10~keV \mbox{X-ray} luminosity, associated 
with the power law, by a factor 20~(see text for details).
