Summary ¶

Masks bins based on muparser expression

Properties ¶

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	An input workspace.
Criterion	Input	string		Masking criterion as a muparser expression; y: bin count, e: bin error, x: bin center, dx: bin center error, s: spectrum axis value.
OutputWorkspace	Output	MatrixWorkspace	Mandatory	An output workspace.

Description ¶

This algorithm masks bins according to the criteria specified as a muparser expression. The variables entering the criteria are reserved as follows:

y : count in a bin (arbitrary units)
x : the bin center (arbitrary units)
e : the standard deviation on the count
dx : the error on the bin center
s : the value of spectrum axis, which has to be SpectraAxis or NumericAxis.

Usage ¶

Example - MaskBinsIf

CreateSampleWorkspace(BankPixelWidth=100, NumBanks=1, OutputWorkspace='out')
MaskBinsIf(InputWorkspace='out', Criterion='s>10 && s<20 && x>1000 && x<2000', OutputWorkspace='out')
