voigt_integrate

mcalf.profiles.voigt.voigt_integrate(x, s, g, clib=False, **kwargs)

Voigt function implementation (calculated by integrating).

The default Voigt implementation.

Parameters:

• x (numpy.ndarray) – Wavelengths to evaluate Voigt function at.

• 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. If the C extensions is not installed, will default to false.

Returns:

result – The value of the Voigt function here.

Return type:

numpy.ndarray, shape=`x.shape`
