Analysing the thermal structure of brightenings. EM loci curves (left column), DEM distributions (middle column) and an estimate of flux contribution of the DEM at different temperatures (right) are shown for the brightenings Br7 (top row) and Br26 (bottom row). In the DEM plots (middle column), the blue horizontal segments mark the modes of the distribution of DEMs at each temperature bin, the green boxes indicate 50% coverage, and the dashed red line is the nominal best-fit (see text).
