ess.reduce.time_of_flight.eto_to_tof.detector_ltotal_from_straight_line_approximation(detector, source_position, sample_position, gravity)[source]#

Compute Ltotal for the detector pixels.

This is a naive straight-line approximation to Ltotal based on basic component positions.

Parameters:

  • detector (EmptyDetector[TypeVar(RunType)]) – Data array with detector positions.

  • source_position (Position[NXsource, TypeVar(RunType)]) – Position of the neutron source.

  • sample_position (Position[NXsample, TypeVar(RunType)]) – Position of the sample.

  • gravity (nexus.types.GravityVector (scipp.Variable)) – Gravity vector.

Return type:

DetectorLtotal[TypeVar(RunType)]
