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.
