(a) Cumulative burst fluence for interval B (33 bursts). Each vertical line is a burst. The dot‐dashed line represents a steady rate of 392 counts day⁻¹. (b) Corresponding reservoir energy. This is modeled assuming a constant power input into a reservoir, which releases the energy as bursts. One count equivalent corresponds to the emission of ~﹩4\times 10^{38}﹩ ergs of X‐rays/γ‐rays.
