Light curves of the 2012 soft state transition (see also Yoshikawa et al. 2015). Top panel: 15–50 keV Swift/BAT (light gray) and 2–4 keV MAXI/GSC (red) light curves anti-correlate, indicative of spectral softening as seen by INTEGRAL/ISGRI in the 2011 hard X-ray dip. The arrows indicate the times of the Swift/XRT observations. Bottom panel: evolution of the disk (green) and Comptonized fluxes (blue) from Swift/XRT compps fits. We note how, for the only time during the ten-year outburst of Swift J1753.5–0127, the diskbb component emits most of the radiative flux.
