Properties

Name	Direction	Type	Default	Description
InputWorkspace	Input	MatrixWorkspace	Mandatory	An input MatrixWorkspace with time-of-flight units along X-axis and defined instrument with defined sample
PeaksWorkspace	InOut	PeaksWorkspace	Mandatory	Workspace with Peaks to be integrated. NOTE: The peaks MUST be indexed with integer HKL values.
RegionRadius	Input	number	0.35	Only events at most this distance from a peak will be considered when integrating
SpecifySize	Input	boolean	False	If true, use the following for the major axis sizes, else use 3-sigma
PeakSize	Input	number	0.18	Half-length of major axis for peak ellipsoid
BackgroundInnerSize	Input	number	0.18	Half-length of major axis for inner ellipsoidal surface of background region
BackgroundOuterSize	Input	number	0.23	Half-length of major axis for outer ellipsoidal surface of background region
OutputWorkspace	Output	PeaksWorkspace	Mandatory	The output PeaksWorkspace will be a copy of the input PeaksWorkspace with the peaks’ integrated intensities.
CutoffIsigI	Input	number	Optional	Cuttoff for I/sig(i) when finding mean of half-length of major radius in first pass when SpecifySize is false.Default is no second pass.
NumSigmas	Input	number	3	Number of sigmas to add to mean of half-length of major radius for second pass when SpecifySize is false.
IntegrateInHKL	Input	boolean	False	If true, integrate in HKL space not Q space.
IntegrateIfOnEdge	Input	boolean	True	Set to false to not integrate if peak radius is off edge of detector.Background will be scaled if background radius is off edge.
AdaptiveQBackground	Input	boolean	False	Default is false. If true, BackgroundOuterRadius + AdaptiveQMultiplier * |Q| and BackgroundInnerRadius + AdaptiveQMultiplier * |Q|
AdaptiveQMultiplier	Input	number	0	PeakRadius + AdaptiveQMultiplier * |Q| so each peak has a different integration radius. Q includes the 2*pi factor.
UseOnePercentBackgroundCorrection	Input	boolean	True	If this options is enabled, then the top 1% of the background will be removedbefore the background subtraction.
GetUBFromPeaksWorkspace	Input	boolean	False	If true, UB is taken from peak workspace.
SatelliteRegionRadius	Input	number	Optional	Only events at most this distance from a satellite peak will be considered when integration
SatellitePeakSize	Input	number	Optional	Half-length of major axis for satellite peak ellipsoid
ShareBackground	Input	boolean	False	Whether to use the same peak background region for satellite peaks.
SatelliteBackgroundInnerSize	Input	number	Optional	Half-length of major axis for the inner ellipsoidal surface of background region of the satellite peak
SatelliteBackgroundOuterSize	Input	number	Optional	Half-length of major axis for the outer ellipsoidal surface of background region of the satellite peak

Description

Overview

As IntegrateEllipsoids v1 and IntegrateEllipsoids v2 but based on input it automatically detects which of the two versions to trigger. Please refer to the docs of the other two for proper useage and acceptable inputs.
