Top: DEM for the Parkinson (1975) active region spectrum and the present elemental abundances. The ion and the wavelength (Å) is given. The numbers in parentheses are the ratios between predicted and observed intensities. The points are plotted at the effective temperature T_eff, and at the theoretical vs. the observed intensity ratio multiplied by the DEM value. Bottom: same DEM, but with the points plotted at the temperature of the maximum of the G(T).
