The data and time-decomposed components for Flare F2. The first panel shows the measured data; the second shows the time-decomposed thermal emission; the third shows the time-decomposed nonthermal emission; the fourth panel shows the measured and time-decomposed backgrounds. In the fourth panel, a preflare background is overplotted on the decomposition. As in the case of Flare F1, the decomposition technique captures the background when its intensity is at least the order of that of the flare, despite the time-varying nature of RHESSI’s background. Some of the background at higher energies gets attributed to the thermal component, which we ignore because its error is ≥50% of the value.
