IndirectDiffScan v1

Summary

Runs an energy transfer reduction for an inelastic indirect geometry instrument.

Properties

Name	Direction	Type	Default	Description
InputFiles	Input	str list		Comma separated list of input files
LoadLogFiles	Input	boolean	True	Load log files when loading runs
Instrument	Input	string	Mandatory	Instrument used during run. Allowed values: [‘IRIS’, ‘OSIRIS’]
SpectraRange	Input	int list	0,1	Comma separated range of spectra number to use.
SampleEnvironmentLogName	Input	string	sample	Name of the sample environment log entry
SampleEnvironmentLogValue	Input	string	last_value	Value selection of the sample environment log entry. Allowed values: [‘last_value’, ‘average’]
OutputWorkspace	Input	string	Output	Workspace group for the resulting workspaces.

Description

This algortithm is to speed up the workflow for Indirect Inelastic diffraction reduction. Uses ISISIndirectDiffractionReduction in diffspec mode with several parameters at fixed values. Also extracts the temperature from each run and creates a workspace of all runs with respect to temperature.

Usage

Example - Running IndirectDiffScan.

ISISIndirectDiffractionReduction(InputFiles='IRS21360.raw',
                                 OutputWorkspace='DiffractionReductions',
                                 Instrument='IRIS',
                                 SpectraRange=[105,112])

ws = mtd['DiffractionReductions'].getItem(0)

print('Workspace name: %s' % ws.name())
print('Number of spectra: %d' % ws.getNumberHistograms())
print('Number of bins: %s' % ws.blocksize())

Output:

Workspace name: iris21360_diffspec_red
Number of spectra: 1
Number of bins: 1934
