ess.estia.conversions.divergence_angle# ess.estia.conversions.divergence_angle(position, sample_position, detector_rotation)[source]# Angle between the scattering ray and the ray that travels parallel to the sample surface when the sample rotation is zero. Parameters: position (Variable) – Detector position where the neutron was detected. sample_position (Variable) – Position of the sample. detector_rotation (Variable) – Rotation of the detector from its zero position. Returns: The divergence angle of the scattered beam.
