Notes. (1) Time intervals where the blueshifted ionized absorber is measured by fitting the XSTAR table. (i), (ii), and (iii) are intervals during the main flare indicated in Fig. 4, and A and B intervals are 0–30 ks and 30–60 ks of the observation, respectively. The spectra taken from the A and B intervals are shown in Fig. 7. A rise in line core flux occurs, as examined in Sect. 3.3.3. (2) Photon index of the power-law continuum. (3) Logarithmic value of the ionization parameter ξO of the outflowing absorber in erg cm s-1. (4) Column density of the absorber in units of 1022 cm-2. (5) Blueshift of the absorber in units of light velocity.
