Doppler speeds for the remaining 5 flares studied. Each subfigure shows speeds calculated for each method. “Sun-as-a-star” speeds are plotted in the left-hand panels, while “flare-excess” speeds are on the right. The “flare-excess” speeds are plotted for only a short period of time, corresponding to when the lightcurve in Ly-β is 2σ above its pre-flare mean. The “flare-excess” time-ranges are indicated on the “Sun-as-a-star” plots by the dashed vertical lines. Overplotted in grey are the normalised Ly-β lightcurves.

This figure is made of several images, please see below:
