Upper left: AstroSat/LAXPC light curve of GX 5-1 of FB & EFB in 6–20 keV with 5 s bins. Upper right: the LAXPC hardness–intensity diagram (HID) of the GX 5-1 of FB & EFB with hard colour computed using the background-subtracted count rates in 10–20 keV divided by that in 6–10 keV and intensity represented by the total count rate in 6–20 keV. Bottom left: Variation of the hardness with respect to time. Bottom right: The portion of 0.3–8 keV AstroSat/SXT light curve, which is simultaneous with LAXPC, is shown. See Section 4.1.
