Notes. The C-statistics refer to the final best-fit, where all obscuration, absorption, emission and extinction effects are taken into account. Expected C-statistics are calculated as described in Kaastra (2017). All quoted errors refer to the statistical uncertainties at the 68.3% confidence level. Frozen parameters are indicated with (f), which are mainly frozen to values given in Paper I. Coupled parameters are indicated with (c). Both Models M1 and M2 use one photoionized component for the obscurer, while Model M3 uses two photoionized components. The continuum of the reflection component is coupled to that of the power-law component observed on 2019-11-15 for both Models M1 and M3 and 2016-12-05 for Model M2.
