Notes. The model equals that fitted to the Suzaku data. The simultaneous fit consists of time-dependent parameters individually fitted to each observation, and time-independent parameters that are equal for all observations, denoted with quotation marks. The symbol marks parameters adopted from the simultaneous fit of the Suzaku observations. The redshift is frozen to the systemic value of z = 0.003859 (de Vaucouleurs et al. 1991). All spectra are additionally absorbed by a cold column of Galactic absorption of 1.99 × 1020 cm-2 (Kalberla et al. 2005). Normalizations are given in units of ph keV-1 cm-2 s-1 at 1 keV.
