NuSTAR 3–79 keV light curve of V404 Cyg divided into GTIs that total 30 000 counts (numbered). The numbers for GTIs that include count rates exceeding 1050 cts s⁻¹ are not shown (excluding GTIs 13 and 14), and the data points are shown in gray with a reduced point size. The coloring scheme corresponds to the spectral shape shown in Fig. 5, with every other GTI shown in a different hue for clarity.
