Upper panel: bolometric light curve of SMC X-3 obtained with the Swift/XRT telescope (black points). Luminosity is calculated from the unabsorbed flux under assumption of the distance to the source d = 62 kpc and bolometric correction factors from Fig. 1. Gray dots represent flux in the 15–50 keV band from the Swift/BAT monitor (in the units of mCrab, right axis). Green vertical dotted lines correspond to the times of the periastron passages. Bottom panel: evolution of the photon index and ratio of fluxes (F0.5 − 10 keV + F15 − 50keV) /F0.5 − 10 keV over the outburst are shown with black and blue points, respectively. Vertical dash-dotted lines correspond to the times of the NuSTAR observations.
