devctrl.data.spectrum.transforms.interpolate_to_wavelengths

interpolate_to_wavelengths(sdata: NDArray, columns: list[str], wavelengths: list | NDArray, **interp_kw) → tuple[NDArray, list[str]]

Interpolate spectrum data and sample all data columns at certain wavelengths.

Parameters:

• sdata – Spectrum data

• columns – List of columns of sdata. Must contain wl

• wavelengths – Array of wavelengths to sample at.

• interp_kw – Keyword arguments to pass to numpy.interp, e.g. left or right

Returns:

sdata at sampled at wavelengths
