SRTs of SEEs relative to the times of the main nonthermal STIX peak and the type III burst onset. (a): TSA SRTs relative to main nonthermal STIX peak. (b): TSA SRTs relative to type III onset. (c): VDA SRTs relative to main nonthermal STIX peak. (d): VDA SRTs relative to type III onset. Impulsive events are shown in blue, gradual ones in red, and the black histogram outlines represent all events. Dotted lines show the medians of the distributions for impulsive and gradual events.
