Summary

Creates a resolution workspace for an indirect inelastic instrument.

Properties

Name	Direction	Type	Default	Description
InputFiles	Input	str list		Comma seperated list if input files
Instrument	Input	string	Mandatory	Instrument used during run. Allowed values: [‘IRIS’, ‘OSIRIS’, ‘TOSCA’]
Analyser	Input	string	Mandatory	Analyser used during run. Allowed values: [‘graphite’, ‘mica’, ‘fmica’]
Reflection	Input	string	Mandatory	Reflection used during run. Allowed values: [‘002’, ‘004’, ‘006’]
DetectorRange	Input	long list	0,1	Range of detetcors to use in resolution calculation.
BackgroundRange	Input	dbl list	0,0	Energy range to use as background.
RebinParam	Input	string		Rebinning parameters (min,width,max)
ScaleFactor	Input	number	1	Factor to scale resolution curve by
LoadLogFiles	Input	boolean	True	Option to load log files
OutputWorkspace	Output	Workspace	Mandatory	Output resolution workspace.

Description

Creates a resolution workspace for an inelastic indirect sample run by summing all spectra in the energy transfer and subtracting a flat background to give a single resolution curve.

Rebinning and intensity scaling can optionally be applied to the result.

Example - Running IndirectResolution.

resolution = IndirectResolution(InputFiles='IRS26173.raw',
                                Instrument='IRIS',
                                Analyser='graphite',
                                Reflection='002',
                                DetectorRange=[3, 53],
                                BackgroundRange=[-0.16, -0.14],
                                RebinParam='-0.175,0.002,0.175')

print('Number of histograms: {:d}'.format(resolution.getNumberHistograms()))
print('Number of bins: {:d}'.format(resolution.blocksize()))

Output:

Number of histograms: 1
Number of bins: 175
