GroupToXResolution v1#

Summary#

Groups points within intervals given by the Dx into single points

Name	Direction	Type	Default	Description
InputWorkspace	Input	`MatrixWorkspace`	Mandatory	An input workspace with Dx values.
OutputWorkspace	Output	`MatrixWorkspace`	Mandatory	The grouped workspace.
FractionOfDx	Input	number	0.2	A fraction of Dx to group the points to.

This algorithm groups the points of a single histogram workspace according to the X resolution stored in the DX array.

The figure below shows schematically how the grouping procedure proceeds.

Select first ungrouped point \(i\). The X resolution (DX) for this point is \(D_{i}\).
Calculate grouping width \(w_{i} =\) FractionOfDx * \(D_{i}\).
Select ungrouped points within \(w_{i}\) from point \(i\).
Calculate the average X, average Y, and the square root of the averaged squared sums of E of the selected points.
Calculate new resolution \(D^{\circ} = \sqrt{D_{i}^{2} + (0.68 \Delta X)^{2}}\) where \(\Delta X\) is span of the X values of the selected points.
Replace the selected points with a single grouped point.
Return to 1.
