(a) and (b) Histograms of the Fe XXIV line intensity and nonthermal velocity within the magenta box marked in Figure 3. (c)–(g) Scatterplots of the Fe XXIV line intensity and nonthermal velocity within the magenta box (black dots) and at the locations marked by the green dotted line (green diamonds) and the cyan dashed–dotted line (cyan asterisks) in Figure 3. (h) Correlation coefficients between the line intensity and nonthermal velocity denoted by the green diamonds and cyan asterisks in panels (c)–(g).
