ess.reduce.nexus.workflow.assemble_beamline(detector, source_position, sample_position, gravity)[source]#

Add beamline information (gravity vector, source- and sample-position) to detector.

This is performed separately and after get_calibrated_detector() to avoid as false dependency of, e.g., the reshaped detector numbers on the sample position. The latter can change during a run, e.g., for a rotating sample. The detector numbers might be used, e.g., to mask certain detector pixels, and should not depend on the sample position.

Parameters:

detector (CalibratedDetector[TypeVar(RunType, nexus.types.BackgroundRun (int), nexus.types.EmptyBeamRun (int), nexus.types.SampleRun (int), TransmissionRun[nexus.types.SampleRun (int)], TransmissionRun[nexus.types.BackgroundRun (int)], nexus.types.VanadiumRun (int))]) – NeXus detector group.
source_position (Position[NXsource, TypeVar(RunType, nexus.types.BackgroundRun (int), nexus.types.EmptyBeamRun (int), nexus.types.SampleRun (int), TransmissionRun[nexus.types.SampleRun (int)], TransmissionRun[nexus.types.BackgroundRun (int)], nexus.types.VanadiumRun (int))]) – Position of the neutron source.
sample_position (Position[NXsample, TypeVar(RunType, nexus.types.BackgroundRun (int), nexus.types.EmptyBeamRun (int), nexus.types.SampleRun (int), TransmissionRun[nexus.types.SampleRun (int)], TransmissionRun[nexus.types.BackgroundRun (int)], nexus.types.VanadiumRun (int))]) – Position of the sample.
gravity (nexus.types.GravityVector (scipp.Variable)) – Gravity vector.

Return type:

CalibratedBeamline[TypeVar(RunType, nexus.types.BackgroundRun (int), nexus.types.EmptyBeamRun (int), nexus.types.SampleRun (int), TransmissionRun[nexus.types.SampleRun (int)], TransmissionRun[nexus.types.BackgroundRun (int)], nexus.types.VanadiumRun (int))]
