voigt_nobg
- mcalf.profiles.voigt.voigt_nobg(x, a, b, s, g, clib=True)[source]
Voigt function with no background (Base Voigt function).
This is the base of all the other Voigt functions.
- Parameters
x (numpy.ndarray) – Wavelengths to evaluate Voigt function at.
a (float) – Amplitude of the Lorentzian.
b (float) – Central line core.
s (float) – Sigma (for Gaussian).
g (float) – Gamma (for Lorentzian).
clib (bool, optional, default=True) – Whether to use the complied C library or a slower Python version. If using the C library, the accuracy of the integration is reduced to give the code a significant speed boost. Python version can be used when speed is not a priority. Python version will remove deviations that are sometimes present around the wings due to the reduced accuracy.
- Returns
result – The value of the Voigt function here.
- Return type
numpy.ndarray, shape=`x.shape`
