Notes. The corresponding continuum properties are provided in Table 5. Explanation of labels: ^(a) the spectral models are described in Table 2; ^(b) iron abundance relative to solar iron abundance; ^(c) ionisation parameter as defined in reflion; ^(d) power-law dependence of emissivity; ^(e) black hole angular momentum; ^(f) fixed. All errors are provided for the 90% confidence level.
