ess.reduce.nexus.workflow.to_transformation#
- ess.reduce.nexus.workflow.to_transformation(chain, interval)[source]#
Convert transformation chain into a single transformation matrix.
If one or more transformations in the chain are time-dependent, the time interval is used to select a specific time point. If the interval is not a single time point, an error is raised. This may be extended in the future to a more sophisticated mechanism, e.g., averaging over the interval to remove noise.
- Parameters:
chain (
NeXusTransformationChain[TypeVar(Component,NXdetector,NXsample,NXsource,NXdisk_chopper,NXcrystal,nexus.types.Monitor1(int),nexus.types.Monitor2(int),nexus.types.Monitor3(int),nexus.types.Monitor4(int),nexus.types.Monitor5(int),nexus.types.IncidentMonitor(int),nexus.types.TransmissionMonitor(int)),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))]) – Transformation chain.interval (
TimeInterval[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))]) – Time interval to select from the transformation chain.
- Return type:
NeXusTransformation[TypeVar(Component,NXdetector,NXsample,NXsource,NXdisk_chopper,NXcrystal,nexus.types.Monitor1(int),nexus.types.Monitor2(int),nexus.types.Monitor3(int),nexus.types.Monitor4(int),nexus.types.Monitor5(int),nexus.types.IncidentMonitor(int),nexus.types.TransmissionMonitor(int)),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))]
