Notes. The ±0.10 dex error comes from the small uncertainty on the spectrum peak position on which these estimates are based. For a = 0, the two models give almost the same results (i.e. disk thickness and relativistic effects are negligible); for a = 0.9982, the two models give different results by a factor of ∼1.2 − 1.3. For comparison, we show in brackets also the SS results.
