Temporal evolution of the Swift/XTE count rate (pink) from the LHS to the HSS and back, shown from top to bottom. Comptonized fraction f (blue), seed photon temperature Ts (black), Nbmc (green) and Γ (red) during the MJD = 58509–58734 outburst transition set. We note that the Comptonized fraction f = A/(A + 1) characterizes the fraction of the soft photons illuminating the Compton cloud (CC), and subsequently up-scattered in the CC hot plasma. Vertical bright blue, hazel and white strips indicates the LHS, IS, and HSS spectral states, correspondingly (as in Fig. 3).
