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

Description

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.

Usage

Warning

This algorithm is not really intended for use at the command line, but is used within DgsReduction.
