Table 2

Global and peak flare temperatures retrieved from the observation of the two TRAPPIST-1 flares.

Notes. The global flare temperatures take the total flux into account, whereas the peak flare temperatures are calculated using the flux within the FWHM. For comparison, the temperatures inferred from the SED of the individual flares are also shown.
