Notes. Only fits with < 2 are shown. is the column density for the neutral absorber in units of 1022 cm−2. kbb, kTdbb and kpo are the normalisations of the blackbody, disc blackbody and the power-law components in units of [(Rin/D10)2], [(Rin/D10)2 cosθ] and [ph keV−1 cm−2 s−1 at 1 keV], respectively, Rin being the radius in km, D10 the distance in units of 10 kpc and θ the inclination of the source. knth is the normalisation of the nthcomp component. kTbb/kTdbb/kTe are the temperatures of the blackbody/disc blackbody components and electrons in units of keV and Γ the index of the power law. F is the unabsorbed flux of the continuum in units of erg cm−2 s−1. t indicates that a parameter was tied for all the observations. f indicates that a parameter was fixed during the fits.
