dem.txt : an ASCII text file containing the DEM distribution that can be read into CHIANTI. chianti.save : a save file containing a structure for the output of the CHIANTI spectral synthesis and a structure describing the input parameters for the DEM. The spectrum is from 1 to 500 Angstroms at 22.5 mA spectral resolution.
