A comparison of GRB 221009A with all of those observed by XRT. The gray scales indicate the number of GRBs in each (time, brightness) bin; the blue light curve is GRB 221009A, with two notable bright GRBs, GRB 130427A (purple) and GRB 080319B (orange) shown for comparison. Top: observer frame, 0.3–10 keV observed flux light curves. Bottom: comoving-frame, 0.3–10 keV intrinsic (unabsorbed) luminosity light curves; the gray-scale sample data includes only those GRBs with published redshifts.
