colour.phenomena.sky_polarisation_Wilkie2021(dataset: SkyDataset_Wilkie2021, parameters: SkyParameters_Wilkie2021, wavelength: ArrayLike) → NDArrayFloat[source]#

Compute degree of polarisation for given wavelength.

Parameters:

dataset (SkyDataset_Wilkie2021) – Loaded dataset from load_dataset_Wilkie2021().
parameters (SkyParameters_Wilkie2021) – Sky parameters from compute_sky_parameters_Wilkie2021().
wavelength (ArrayLike) – Wavelengths in nanometers.

Returns:

Degree of polarisation. The result is negated from the internal model coefficients following the convention of the reference C++ implementation.

Return type:

numpy.ndarray

Raises:

ValueError – If the dataset does not contain polarisation data.
