- 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 detector group.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:
CalibratedBeamline[TypeVar(RunType)]
