Fig. 8
Corona: variability of the spectral parameters along the segments. The electron temperature is shown in the second panel, the optical depth in the third, and the 0.01–100 keV flux in the bottom one. Interval I is represented with a solid line, II with a dashed line, and III with a dotted line. The top panel shows the MECS rate for comparison; two bursts are shown for clarity.
