Histograms of the measured intensity increase between the flare and post-WLF states (blue, equivalent to the difference of continuum intensity of the red and blue profiles in Fig. 6) and the determined chromospheric continuum contribution to this increase (olive, equivalent to the difference of continuum intensity of the red and olive profiles in Fig. 6), both assessed in the region of interest shown by the blue contour in Fig. 1. Left panel: values normalised by the continuum intensity of the quiet Sun , Right panel: values normalised by the local continuum intensity in the post-WLF state I₂.
