Notes. When the reduced  is close to the value of 2.0, the errors (90% confidence level) associated with the model parameters were obtained by using the steppar command within XSPEC. Hydrogen column-densities are in units of 1022 cm-2. Fixed values in the fits are indicated in square brackets. In the first column, the character M represents the MOS 1 and MOS 2 data sets, and p stands for the pn data. A line over the character (or set of characters) indicates that, in the corresponding fit, the model normalizations were assumed to be identical for the overlined data sets.
