lyman: Voigt absorption profiles for H I or He II Lyman series

This model calculates the Voigt absorption profiles for the H I and He II Lyman series.

par1 n: H I or He II column density ( $10^{22}$ atoms/cm)

par2 b: b value (km/s)

par3 z: Redshift

par4 ZA: Atomic number of species being calculated.
