Fit of the spectrum of episode 2, with a Band model (upper panel) and a black body plus a power-law model (lower panel). Both models fit the entire energy range well, with a chi squared of 0.79 and 0.84, respectively. The data points have been grouped according a signal-to-noise ratio of N = 10, and rebinned at higher energies in order to have better statistics and reduce the error bars.
