par1 = ![]() |
line wavelength in Angstrom |
par2 = ![]() |
line width in Angstrom |
Norm = K | total photons/cm![]() |
For zagauss the corresponding formula is:
![\begin{displaymath}
A(\lambda) = K {(1+z)\over{\sigma\sqrt{2\pi}}}
\exp(-(\lambda/(1+z)-\lambda_l)^2/2\sigma^2)
\end{displaymath}](img122.png)
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
.
