Notes. Errors are quoted at 90% confidence. (f) Parameter fixed for consistency between fit regions.

(a)

Observed flux in units of 10-14 erg cm-2 s-1;

(b)

absorption corrected luminosity in units of 1034 erg s-1 assuming a distance of 60 kpc.

(c)

SMC absorption for all nebular spectra was frozen to the column density obtained from the XMM-Newton observation .
