lorentz
(wvl, wvl0, factor=1.0)[source] [edit on github]¶ Lorentz profile filter with the exception that all factors are in wavelength units rather than frequency as the lorentz profile is usually defined.
Parameters: wvl :
ndarray
Wavelength array
wvl0 :
float64
Wavelength filter should be centered on.
factor :
float64
Value of the so-called constant gamma
integrated value is unity
the FWHM is 2*gamma
.. math::
L = frac{1}{pi gamma} frac{ gamma^2}{(lambda - lambda_0)^2 + gamma^2}
