agauss, zagauss: gaussian line profile in wavelength
space
A simple gaussian line profile. If the width is then it is treated
as a delta function. The zagauss variant computes a redshifted
gaussian.
where:
par1 = |
line wavelength in Angstrom |
par2 = |
line width in Angstrom |
Norm = K | total photons/cm |
For zagauss the corresponding formula is:
and the parameters are:
par1 = |
line wavelength in Angstrom |
par2 = |
line width in Angstrom |
par3 = z | redshift |
Norm = K | total photons/cm |
The line is truncated at the point that the integrated flux under the line is
within a critical value of the total flux. This critical value can be
changed using xset LINECRITLEVEL. The default critical value is
.
