If multiple files, the parameter from SampleLog to use as an index when conjoined.

Transpose

Input

boolean

True

Transpose the result.

Sum

Input

boolean

False

Sum along the scan

ComponentsToMask

Input

string

Comma separated list of component names to mask, for instance: tube_1, tube_2

Description

This algorithm reduces data acquired by the diffraction detectors of IN16B indirect geometry instrument at ILL.

Ultimately, it will handle both BATS and Doppler data, but the later is the only one implemented as of now.

Doppler

To reduce data acquired in Doppler mode, this algorithms sums data over all Doppler channels and normalize by monitor counts.

Usage

Example - IndirectILLReductionDIFF

ws = IndirectILLEnergyTransfer(Run='ILL/IN16B/276047.nxs')
print("Reduced workspace has {:d} spectra".format(ws.getItem(0).getNumberHistograms()))
print("and {:d} bins.".format(ws.getItem(0).blocksize()))

Output:

Reduced workspace has 18 spectra
and 512 bins.
