Properties

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	A workspace to mask.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	The masked workspace.
ComparisonWorkspace	Input	MatrixWorkspace	Mandatory	A workspace to compare the InputWorkspace’s binning to.
MaskPartiallyOverlapping	Input	boolean	False	If true, mask also bins that overlap only partially.
RaggedInputs	Input	string	Check	Choose whether the input workspaces have common bins, are ragged, or if the algorithm should check. Allowed values: [‘Check’, ‘Ragged’, ‘Common Bins’]
CheckSortedX	Input	boolean	True	If true, the algorithm ensures that both workspaces have X sorted in ascending order.

Description

This algorithm masks the bins in InputWorkspace which lie in \(X\) range that is not covered by ComparisonWorkspace. The MaskPartiallyOverlapping flag affect the behavior with regards to bins which are partially covered by ComparisonWorkspace. The algorithm works only with the X data sorted in ascending order.

The algorithm currently applies the default masking weight to the bins which does not clear the data.

Optimizations

Some small optimizations are possible via CheckSortedX and RaggedInputs. Make sure the input workspaces fill the expectations before using these properties!

• If there is no doubt that X data in InputWorkspace and ComparisonWorkspace is sorted, the checking for ascending X can be skipped by setting CheckSortedX to False.

• If RaggedInputs is set to 'Check' (the default), the algorithm will check if both InputWorkspace and ComparisonWorkspace are ragged workspaces and choose the processing method accordingly. The test can be skipped by setting RaggedInputs to 'Ragged' or 'Common Bins' which forces a specific processing method.

Usage

Example - MaskNonOverlappingBins

bigWS = CreateSampleWorkspace(XMin=0, XMax=20000)
smallWS = CreateSampleWorkspace(XMin=9000, XMax=11000)
masked = MaskNonOverlappingBins(bigWS, smallWS)
print('It is not (yet) possible to access the bin masking information in Python.')
print('Please check that the correct bins are grayed out in the data view.')

Output:

It is not (yet) possible to access the bin masking information in Python.
Please check that the correct bins are grayed out in the data view.
