ess.estia.conversions.theta(divergence_angle, sample_rotation)[source]#

Angle of reflection.

Computes the angle between the scattering direction of the neutron and the sample surface.

Parameters:

divergence_angle (Variable) – Divergence angle of the scattered beam.
sample_rotation (Variable) – Rotation of the sample from to its zero position.

Returns:

The reflection angle of the neutron.
