- ess.spectroscopy.indirect.kf.detector_geometric_a4(*, sample_analyzer_vector, beam_aligned_unit_vectors)[source]#
Calculate the scattering angle from the incident beam to each detector element
- Parameters:
sample_analyzer_vector (
Variable) – The per detector element analyzer interaction position, as determined bysample_analyzer_vector().beam_aligned_unit_vectors (
BeamAlignedUnitVectors) – Unit vectors defining the coordinate system aligned with the incident beam and gravity. Seescippneutron.conversion.beamline.beam_aligned_unit_vectors().
- Returns:
Variable– The per detector element scattering angle, a4, in degrees.
