xarray.DataArray.kspace.hv_to_kz¶

DataArray.kspace.hv_to_kz(self, hv)[source]¶

Return \(k_z\) for a given photon energy.

Useful when creating overlays on \(hν\)-dependent data.

Parameters:: hv (float | Iterable[float]) – Photon energy in eV.

Note

This will be inexact for hv-dependent cuts that do not pass through the BZ center since we lost the exact angle values, i.e. the exact momentum perpendicular to the slit, during momentum conversion.
