Notes. Model1 consists of a Comptonization component (compPS) and a reflection with emission line (diskline). Model2 consists of a blackbody model (bb) and a double Comptonization component (compTT and compPS with reflection) and the emission line. The two asterisks indicate that the bb component is not required in the I state. When it is added to the model with kTbb fixed to 0.1 keV the value of Nbb is (6 ± 7) × 10-3; the values of the other parameters remain almost unchanged. Uncertainties are at the 90% confidence level for a single parameter.
