From top to bottom. INTEGRAL /ISGRI count rate of the source in the 20–100 keV energy range (the Crab yields about 220 cts/s in this band). Colors and labels indicate the time intervals used for the joint XRT+JEM-X+ISGRI fits reported in Table 1. We also mark in this panel the radio coverage (Trushkin et al. 2011). Swift /XRT lightcurve of the source (time bin 1 ks) in two energy bands (0.3–4 keV and 4–10 keV) and the corresponding HR. Evolution of the temperature and squared root of the normalization constant (proportional to the disk inner radius) of the diskBB component and PL photon index.
