Best-fit broad-band model for XMM-NewtonObs. 2 as described in Sect. 5. The red circles represent the OM data, the purple squares the HST/COS data, the brown diamonds are the scaled FUSEdata and in green are the absorption-corrected EPIC-pn data. The grey line is the disc blackbody component, the dashed magenta is the warm Comptonisation component and the olive colour line represents the broken power-law and includes a Gaussian for modelling the Fe Kαline. The black line is the total model spectrum.
