Caption: Figure 9.
Averaged differential spectra across a Gaussian time window centered on the secondary peak of the flares. The inset panels show the distribution of blackbody fits during the bootstrap procedure described in Section 1. The best-fit temperatures are ﹩17,50{0}_{-1300}^{+4600}﹩ K and ﹩11,50{0}_{-200}^{+300}﹩ K for EVRT-2509887 and EVRT-3586872, respectively. The continuum emission is poorly described by a single blackbody, and both deviate from a thermal spectrum at the end of the spectrum, due to Balmer continuum emission in the blue and “conundruum” in the red.
