NuSTAR FPMA+B background-subtracted light curve in the 3–70 keV. 3–10 keV and 10–70 keV energy ranges are shown in the top, top middle, and bottom middle panels, respectively. In the bottom panels, the ratios of the NuSTAR NuSTAR background-subtracted light curves in the 10–70 keV and 3–10 keV energy bands are reported. All the light curves are extracted using a binning time of 500 s. The color code used in this figure for different ObsID is applied throughout the paper. The solid and dashed black lines indicate the average and the standard error of the mean, respectively.
