Description#

Subtract background from an I(Q) distribution.

The DataDistribution and Background properties can either be the name of a workspace or a file path. If a file path is provided, it will be loaded and assumed to be in units of Q.

The output workspace will be equal to:

`` Output = DataDistribution - ScaleFactor * Background + Constant``
`` ``

The Dq values are propagated from the DataDistribution workspace to the output workspace as-is.

If the OutputDirectory property is filled, the output workspace will be written to disk. Two files will be produced, a 4 column ASCII file and a CanSAS XML file.
