agauss, zagauss: gaussian line profile in wavelength space

A simple gaussian line profile. If the width is ≤ 0 then it is treated as a delta function. The zagauss variant computes a redshifted gaussian.

where:

par1 = λl

line wavelength in Angstrom

par2 = s

line width in Angstrom

Norm = K

total photons cm-2 s-1 in the line

 

For zagauss the corresponding formula is:

and parameter settings are:

par1 = λl

line wavelength in Angstrom

par2 = σ

line width in Angstrom

par3 = z

redshift

Norm = K

total photons cm2s1 in the line
