g2_split#

pynlo.utility.chi2.g2_split(n_eff, a_eff, chi2_eff)[source]#

The 2nd-order nonlinear parameter decomposed according to unit analysis.

Parameters:
n_effarray_like of float

The refractive indices.

a_effarray_like of float

The effective areas.

chi2_effarray_like

The effective 2nd-order susceptibilities.

Returns:
ndarray (2, n)

The unit decomposition of the 2nd-order nonlinear parameter. The first index contains the output factors while the second index contains the input factors.
