Notes. Spectral energy distribution. From first row to last the average corresponds to the five sets of flares shown in Figs. 1 and 4. The two ratios in Cols. 3 to 5 correspond to integrations over the entire flare duration and integrations limited to the TSI flare signal period. The three last columns show mean blackbody and flare parameters that can explain the visible emission at the flare peak time.
