A partial covering fraction absorption. The relative abundances are set by the abund command.
where s(E) is the photo-electric cross-section (NOT including Thomson scattering) (see phabs) and:
par1= n_{H} |
equivalent hydrogen column (in units of 10^{22} atoms cm^{–2}) |
par2= f |
covering fraction (dimensionless) |
The redshifted variant zpcfabs is given by:
where s(E) is the photo-electric cross-section (NOT including Thomson scattering) (see phabs). Relative abundances are as for pcfabs. Parameters are:
par1= n_{H} |
equivalent hydrogen column (in units of 10^{22} atoms cm^{–2}) |
par2= f |
dimensionless covering fraction |
par3= z |
redshift |
