 \caption{Results of the spectrum fits  for the three strongest lines and the underlying
continuum. Line centroids and $\sigma$ are in keV, rates are dead-time corrected
counts/s and line fluences are expressed in photons/cm$^2$. S is the power-law
index of the observed photon spectrum. Error bars result
from the fit with an additional uncertainty of~10\% for the fluences, due to an
uncertainty on  the effective area, added quadratically to the error bar of the
fit.\label{table2} }
