vmeka

An emission spectrum from hot diffuse gas based on the model calculations of Mewe and Gronenschild (as amended by Kaastra - for references see the section on the meka model). The model includes line emissions from several elements. Abundances are the number of nuclei per Hydrogen nucleus relative to the Solar abundances set by the abund command.

par1 	   = 	plasma temperature in keV

par2 	   = 	hydrogen density in cm  

par3-par16 =    Abundances for He, C, N, O, Ne, Na, Mg, Al, Si, S,

                Ar, Ca, Fe, Ni wrt Solar (defined by the abund command)

par17	   = 	redshift, z

K	   = 	 , where D is the distance to the

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