Statistical study of all the events, with comparison between the regions defined by the NW/IN mask. The first column (panels a and d) shows all the events, the second column (panels b and e) shows the events within the NW mask, and the third column (panels c and f) shows the events within the INmask. For each event, the first row shows the brightness temperature excess plotted against the lifetime and the second row shows the brightness temperature excess plotted against the base brightness temperature. The distributions are represented as density maps and the contour lines mark the levels of 0.05, 0.25, 0.5, 0.75, and 0.95. The dotted and dashed lines in panels d, e, and f show the median and mean value, respectively, of the brightness temperature of all pixels within 15″ during the entire dataset. The selected events A–D (Sect. 3.4) are marked in all panels for reference.
