devctrl.data.spectrum.transforms.interpolate_to_energies

interpolate_to_energies(sdata: ndarray[tuple[Any, ...], dtype[_ScalarT]], columns: list[str], energies: list | ndarray[tuple[Any, ...], dtype[_ScalarT]], **interp_kw) → tuple[ndarray[tuple[Any, ...], dtype[_ScalarT]], list[str]]

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

Parameters:

• sdata – Spectrum data

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

• energies – Array of energies to sample at.

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

Returns:

sdata at sampled at energies
