Notes.

(a)

Probability that n consecutive data points in the emission line region are mutually independent.

(b)

Value corresponding to the fit in which the emission line energy is not constrained (see Col. 7 Table 3).

(c)

Value corresponding to the fit in which the emission line is constrained in the 6.4–6.97 keV energy range (see Col. 8 Table 3).
