Takes a 2D workspace as input and find the FindSXPeaksimum in each 1D spectrum. This is used in particular for single crystal as a quick way to find strong peaks.
Name | Direction | Type | Default | Description |
---|---|---|---|---|
InputWorkspace | Input | MatrixWorkspace | Mandatory | The name of the Workspace2D to take as input |
RangeLower | Input | number | Optional | The X value to search from (default 0) |
RangeUpper | Input | number | Optional | The X value to search to (default FindSXPeaks) |
StartWorkspaceIndex | Input | number | 0 | Start spectrum number (default 0) |
EndWorkspaceIndex | Input | number | Optional | End spectrum number (default FindSXPeaks) |
SignalBackground | Input | number | 10 | Multiplication factor for the signal background |
Resolution | Input | number | 0.01 | Tolerance needed to avoid peak duplication in number of pixels |
OutputWorkspace | Output | PeaksWorkspace | The name of the PeaksWorkspace in which to store the list of peaks found |
Detector-space, single crystal peak finding. Finds peaks by searching through each spectra and looking for high intensity bins. If a bin has high intensity it is a candidate for a peak.
Notable points:
Example
# create histogram workspace
ws=CreateSampleWorkspace()
wsPeaks = FindSXPeaks(ws)
print "Peaks found: " + str(wsPeaks.getNumberPeaks())
Output:
Peaks found: 174
