Notes. For each of the four observation epochs, we list the χ2-values of the best fit (Col. 2; Gaussian with adapted centroid and width), then the intensity-fitted shape of the line as determined in the time-integrated results (Fig. 2) (Col. 3), and finally (Col. 4) the intensity-fitted line shape of the last epoch. The degrees of freedom of the fits are given in Col. 2 in brackets. The discrepancy of the thus-adopted line shape in each of the epochs is given in sigma units in brackets in Cols. 3, 4. The lefthand table gives the results for the 10 keV bin data (center column in Fig. 4), the righthand table gives the results for the 2 keV bin data (left column in Fig. 4)
