Time evolution throughout the superflare for parameters derived from the XMM-Newton and TESS data. Upper panel: flaring plasma temperature and EM. Middle panel: flaring plasma abundances and electron density. The abundances of all elements are tied to the Fe abundance using the ratios determined for the quiescent state from the RGS spectrum that are listed in Table C.1. Lower panel: thermal energy in the flaring plasma, compared with the total radiated energy in the X-ray and optical bands.
