DgsPreprocessData v1¶

Summary ¶

Preprocess data via an incident beam parameter.

Properties ¶

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	An input workspace.
InputMonitorWorkspace	Input	MatrixWorkspace		A monitor workspace associated with the input workspace.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	The name for the output workspace.
TofRangeOffset	Input	number	0	An addition to the TOF axis for monitor integration.
ReductionProperties	Input	string	__dgs_reduction_properties

This algorithm is responsible for normalising data via a given incident beam parameter. This parameter, IncidentBeamNormalisation, is controlled from the reduction property manager. It can have the values None, ByCurrent or ByMonitor. For SNS, monitor workspaces need to be passed. Parameters in italics are controlled by the instrument parameter file (IPF) unless provided to the algorithm via a property manager. The mappings are given below.

Parameter	IPF Mapping
MonitorIntRangeLow	norm-mon1-min
MonitorIntRangeHigh	norm-mon1-max

Parameters in italics with dashed perimeters are only controllable by the IPF name given. All underlined parameters are fixed via other input methods. If normalisation is performed, a sample log called DirectInelasticReductionNormalisedBy is added to the resulting workspace with the normalisation procedure used.
