Left: Distribution of Hα line core widths (following the definition by Leenaarts et al. 2012) for the whole time series. Right: Corresponding line widths according to the definition by Molnar et al. (2019). The whole box, QS and EN regions are separately plotted in blue, black and red, and mean and median values for the three sets of pixels are indicated with a dot-dashed and dashed lines in the respective colours. Please note the difference in ranges for linewidths axes in the two plots.
