Evolution of Swift/XRT (0.3–10 keV, top panel) and MAXI/GSC flux (bottom panel) in 2–20 keV, 2–4 keV, 4–10 keV and 10–20 keV energy ranges during 58450–58800 MJD observations of MAXI J1348–630. Vertical bright blue, hazel, and white strips indicates the LHS, IS and HSS spectral states, correspondingly (for identification of spectral states see Sect. 3.1). Pink arrow (at top of the panel) indicate the time interval under our study (from January to September, 2019) for data sets listed in Table 2.
