Time difference between SRT (determined with VDA) and solar events plotted versus heliocentric distance. The solar reference times used correspond to the main STIX HXR peak (left) and the RPW type III onset (right). The top row shows gradual events, the bottom row impulsive events. Error bars indicate the one-sigma VDA fit uncertainties. Also shown is the number of events, a linear fit (dotted line) with fit parameters and uncertainties, the Pearson correlation coefficients C, and the p-values p.
