Summary

This algorithm inspects Magnetism Reflectometer data and populates meta-data.

Properties

Name	Direction	Type	Default	Description
Workspace	Input	Workspace	Mandatory	Input workspace
UseROI	Input	boolean	True	If true, use the meta-data ROI rather than finding the ranges
UpdatePeakRange	Input	boolean	False	If true, a fit will be performed and the peak ranges will be updated
UseROIBck	Input	boolean	False	If true, use the 2nd ROI in the meta-data for the background
UseTightBck	Input	boolean	False	If true, use the area on each side of the peak to compute the background
BckWidth	Input	long	10	If UseTightBck is true, width of the background on each side of the peak
ForcePeakROI	Input	boolean	False	If true, use the PeakROI property as the ROI
PeakROI	Input	long list	0,0	Pixel range defining the reflectivity peak
ForceLowResPeakROI	Input	boolean	False	If true, use the LowResPeakROI property as the ROI
LowResPeakROI	Input	long list	0,0	Pixel range defining the low-resolution peak
ForceBckROI	Input	boolean	False	If true, use the BckROI property as the ROI
BckROI	Input	long list	0,0	Pixel range defining the background
EventThreshold	Input	long	10000	Minimum number of events needed to call a data set a valid direct beam
DirectPixelOverwrite	Input	number	Optional	DIRPIX overwrite value
DAngle0Overwrite	Input	number	Optional	DANGLE0 overwrite value (degrees)

Description

Use by the Magnetism Reflectometer reduction. The algorithm takes in raw event data and determines various parameters such as the reflectivity peak position, the pixel range of the data in the low-resolution direction, the TOF range, etc… This information is stored in the sample logs.
