Gaussian fit for flare SOL2013-05-13T15 (middle panel in Fig. 1). The top panel shows the fit compared to the intensity for a horizontal slice in the middle of the time-distance plot, and the bottom panel shows the trace given by the mean of the Gaussian fit at each height. We can see traces of the spike morphology as an illumination at the bottom of the figure, in addition to the ejection (LPS) morphology, which again is seen as a cloud appearing after the spike.
