Quantitative analysis of the Fe xxi and 131 Å EMs for flare 1. The top row from left to right shows Fe xxi, 1600 Å, and 131 Å intensity. The middle panels show the mean and median (red line) ratios EM(131)/(EM(131)+EM(Fe xxi)) vs. Fe xxi intensity in loops (bin = 400 DN) and kernels (bin = 400 DN), and on the right the ratio EM(131)/(EM(131)+EM(Fe xxi)) vs. intensity of 131 Å (bin = 400 DN s^-1). The bottom panels show the same ratios vs. intensity but as scatter plots. In the loops the mean, standard deviation, and median ratios are 0.54 ± 0.07 and0.55.
