An emission spectrum from hot diffuse gas based on the model calculations of Mewe and Gronenschild (as amended by Kaastra). The model includes line emissions from several elements. Abundances are the number of nuclei per Hydrogen nucleus relative to the cosmic abundances of Anders E. & Grevesse N. (1989) Geochimica et Cosmochimica Acta 53, 197. See the help on the meka model for further references.
