Background Input string   Name of the background workspace or file path
ScaleFactor Input number 1 Scaling factor [Default: 1]
Constant Input number 0 Additive constant [Default:0]
OutputDirectory Input string   Directory to write the output files in [optional]
OutputWorkspace Output MatrixWorkspace Mandatory Workspace containing data from detectors

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.
