SED for the two observed flares in M2. The SEDs are fit with a model where the temperature T_eff and the area parameter a are left as free parameters using emcee again. The flux in z_s-filter is slightly inconsistent with the best-fit black bodies for both flares. The uncertainties of the model are indicated with shaded areas. The uncertainty bars in wavelength should be understood as the respective filter widths. The SED for Flare 2 is multiplied by a constant factor of 2.5 for a better visual comparison between the two SEDs. The purple and orange lines indicate 100 randomly drawn samples from the Markov chain and mark the uncertainty of the fitted dashed best-fit curves.
