Table 6: Parameters of the spectral fits for the extended sources. Stated errors correspond to the 90% confidence level. The global metallicity was set to  $0.3~Z_{\odot}$ for all sources. Fluxes are given in the spectral range 0.4-10 keV, and in units 10-14 ergs cm-2 s-1. Unabsorbed fluxes are corrected for the fitted N(H). The results correspond to a simultaneous fit of all EPIC spectra, except for the NE source, for which only a pn spectrum was available. Constrained fits are also listed below when the fitted N(H) was outside the "allowed'' range (see Sect. 4.1). Note that solutions with $\chi ^2>2$ were not included.
