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

To run these usage examples please first download the usage data, and add these to your path. In Mantid 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)
