The best-fitting parameters of ‘tbabs*(diskbb+kdblur*xilconv*nthcomp+Gaussian’ model for observations A–F. The system parameters are fixed at the same values as Table 2. Errors are not estimated for observations D to F due to bad chi-squared values. †The best-fitting electron temperature of nthcomp were found at their upper limit of 300 keV, and thus they were fixed. *Parameters hit the lower or upper limit. |$^\#$|Chi-squared values for the same fits without Gaussian component, and F-values calculated as |$F=(\Delta \chi ^2/\chi ^2_\nu)/\Delta \nu$|, representing the improvement due to the Gaussian component.
