Description

The generic routine used to reduce diffraction runs from indirect geometry inelastic instruments at ISIS.

Usage

Example - Running ISISIndirectDiffractionReduction.

ISISIndirectDiffractionReduction(InputFiles='IRS21360.raw',
                                 OutputWorkspace='DiffractionReductions',
                                 Instrument='IRIS',
                                 Mode='diffspec',
                                 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
