MSDFit Input boolean False Perform an MSDFit
SumFiles Input boolean False Toggle input file summing or sequential processing
ReducedWorkspace Input string Reduced Workspace group for the resulting workspaces.
ScanWorkspace Input string Scan Workspace for the scan results.

Description

Performs a data reduction from ISISIndirectEnergyTransfer, before performing the ElasticWindowMultiple algorithm over the elastic and inelastic regions of the reduced data to calculate the elastic incoherent scattering factor. There is also an option to perform the MSDFit algorithm.

Usage

Note

To run these usage examples please first download the usage data, and add these to your path. In MantidPlot this is done using Manage User Directories.

Example - IRIS Energy Window Scan

EnergyWindowScan(InputFiles="IRS21360.RAW", Instrument='IRIS', Analyser='graphite',
                         Reflection='002', SpectraRange='3, 50', ElasticRange='-0.5, 0',
                         InelasticRange='0, 0.5', GroupingMethod='Individual', MSDFit=True)
