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.
