Flux-duration distribution of the X-ray flares from Sgr A* in a log-log diagram using DIVA. The color bars represented in the right-hand side of each panel are in units of 1010 s−1 erg−1 s cm2. Left panel: flare flux-duration distribution observed with XMM-Newton and Chandra from 1999 to 2018. The flares beginning before or ending after the GTIs are not represented. Right panel: intrinsic flare density distribution corrected for the observing bias and the error on the flux and duration.
