\tablefoot {First column: distribution as fitted by a single Gaussian law for the ``quiescent'' regime (data set~$D_{\rm QS}$). Second column: distribution fitted by two Gaussian laws, one for the ``quiescent'' regime, the other for the flaring regime (data set~$D$). Decimal logarithms are quoted
to make the comparison with the left panel of Fig.~\ref{doubleGaussian_fit} easier and the flux is expressed in cm$^{-2}$~s$^{-1}$. In the first line the average of fluxes is reported,  while in the second line their~rms.}
