Notes. Errors and upper (lower) limits were computed within XSPEC at 90% confidence level. (a) The parameter was tied to the hydrogen density with the relation logξ = 1.48 − log(n0). Through this relation, asymmetric errors of n0 were first averaged (e.g., see D’Agostini 2003, Chap. 12) and then propagated. (b) log T was left free to vary between 0 and 8, the best value being in this case 7.81.
