Note. Best-fit values of the parameters obtained for the averaged spectrum fitting the emission features with Gaussian profiles. Uncertainties are at the 90% confidence level for a single parameter. The parameters are defined as in XSPEC. The continuum emission is fitted with a blackbody plus a multicolored disk blackbody, diskbb. The four broad emission features are modelled adopting Gaussian components. All components are subject to interstellar absorption.
