Notes. Uncertainties are at the 90% c.l. for each parameter. The parameters are defined as in XSPEC. The model is discussed in the text. The equivalent hydrogen column of the local neutral matter is indicated with NHpc, the covered fraction of the emitting surface is indicated with f. The (d.o.f.) values are obtained taking into account the emission lines reported in Table 2.
