Summary

BASISReduction311 is deprecated (on 2017-03-11). Use BASISReduction instead.

Properties

Name Direction Type Default Description
RunNumbers Input string   Sample run numbers
DoIndividual Input boolean False Do each run individually
NoMonitorNorm Input boolean False Stop monitor normalization
NormRunNumbers Input string   Normalization run numbers
NormWavelengthRange Input dbl list 6.24,6.3 Wavelength range for normalization. default:(6.24A, 6.30A)
EnergyBins Input dbl list -740,1.6,740 Energy transfer binning scheme (in ueV)
MomentumTransferBins Input dbl list 0.4,0.2,3.8 Momentum transfer binning scheme
MaskFile Input string   Directory location for standard masking and grouping files. Allowed extensions: [‘.xml’]
GroupDetectors Input string None Switch for grouping detectors. Allowed values: [‘None’, ‘Low-Resolution’, ‘By-Tube’]

For each property, the algorithm will remember the last value used. If user deletes this value and leaves blank the property field, the default value will be used. Default values are typical of the silicon311 reflection.

Description

Run numbers: The syntax for the run numbers designation allows runs to be segregated into sets. The semicolon symbol ”;” is used to separate the runs into sets. Runs within each set are jointly reduced.

Examples:

  • 2144-2147,2149,2156 is a single set. All runs jointly reduced.
  • 2144-2147,2149;2156 is set 2144-2147,2149 and set 2156. The sets are reduced separately from each other.

If DoIndividual is checked, then each run number is reduced separately from the rest. The semicolon symbol is ignored.

Momentum transfer binning scheme: Three values are required, the lower boundary the bin with the minimum momentum, the bin width, and the upper boundary ofthe bin with the maximum momentum.

Reflection Selector

There are typical values for the properties of the 311 reflection:

Reflection
Energy bins
(micro-eV)
Momentum transfer bins
(inverse Angstroms)
silicon311 -740, 1.6, 740 0.5, 0.2, 3.7

Also the following mask files is associated to the 311 reflection:

Reflection Mask file
silicon311 BASIS_Mask_OneQuarterRemains_SouthBottom.xml

This mask files can be found in the SNS filesystem (/SNS/BSS/shared/autoreduce/new_masks_08_12_2015/)

Usage

Warning

This algorithm is not meant to be run from the command line.
