BASISReduction311-v1.rst 2.27 KiB

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:

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.
