An emission spectrum from hot, diffuse gas based on the model calculations of Raymond and Smith including line emissions from several elements. This model interpolates on a grid of spectra for different temperatures. The grid is logarithmically spaced with 80 temperatures ranging from 0.008 to 80 keV.

par1	 = 	plasma temperature in keV

par2	 = 	Metal abundances (He fixed at cosmic) The elements included are

		C, N, O, Ne, Mg, Si, S, Ar, Ca, Fe, Ni and their relative

		abundances are set by the abund command.

par3	 = 	redshift, z

K	 = 	 , where D is the distance to the

 		source (cm),  and  are the electron and H densities (cm )
