A simple gaussian line profile. If the width is then it is treated as a
delta function. The zgauss variant computes a redshifted gaussian.
where:
par1 | ![]() |
par2 | ![]() |
Norm | ![]() ![]() |
For zgauss the corresponding formula is:
and parameter settings are:
par1 | ![]() |
par2 | ![]() |
par3 | ![]() |
Norm | ![]() ![]() |
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
.
