zvphabs

A redshifted photoelectric absorption with variable abundances using Balucinska-Church and McCammon (ApJ 400, 699) cross-sections. The abundances are specified relative to the Solar abundance table set using the abund command. This model is identical to zvarabs except for the way that the parameters are defined.

where is the photo-electric cross-section (NOT including Thomson scattering) and

par1	   =  	equivalent hydrogen column (in units of   atoms/cm )

par2-par18 = 	abundances for He, C, N, O, Ne, Na, Mg, Al, Si, S,

        	Cl, Ar, Ca, Cr, Fe, Co, Ni wrt to Solar (defined by the abund command)

par19	   = 	redshift
