Posterior distributions of the model parameters fitted in this work in the shape of histograms, along with their correlation plots. Values are computed from the 1.5 Å excess light curve around the sodium D₂ line. Here FL is the flare scaling parameter, Sig is the width of the exoplanetary Gaussian profile, Amp is the amplitude of the exoplanetary Gaussian profile, and off is the normalization constant for the flare model.
