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