Notes. Only the parameters of the three absorbers and those of the reflection component are listed. The mean one-sided errors are the mean of the positive and negative errors. We note that the positive error on the spin is bounded by the maximum spin value of 0.998. Configuration 1b corresponds to the same simulations as for configuration 1 but using the WFI responses (Meidinger et al. 2018). Configuration 3b is identical to configuration 3 but a 5% energy-independent systematic uncertainty has been added to the data. The integration time for configurations 1 to 4, and 7 to 9 is 100 ks; for configurations 5 and 6, this is 25 ks. The source intensity is 1 mCrab in configurations 1 to 4 and 0.5 mCrab in configurations 5 to 9. Configurations 7 to 9 are identical to configuration 3 but the iron abundance, the system inclination, and the disk ionization are allowed to vary, as indicated in Table 3.
