Table of Contents
| Name | Direction | Type | Default | Description |
|---|---|---|---|---|
| InputWorkspace | Input | EventWorkspace | Mandatory | An input event workspace to use as a source for the events. |
| RangeStart | Input | number | Optional | Set the lower bound for sampling the background. |
| RangeEnd | Input | number | Optional | Set the upper bound for sampling the background. |
| OutputWorkspace | Output | MatrixWorkspace | Mandatory | Output event workspace containing a flat background. |
This creates a new event workspace from an existing one by sampling an area of the source workspaces background and then using this to create a new workspace that covers the same data range as the input workspace.
Example: Extract the background into another workspace
ws = CreateSampleWorkspace("Event","Multiple Peaks")
wsOut=CreateFlatEventWorkspace(ws,RangeStart=15000,RangeEnd=18000)
#to compare we need to match the bins
wsOut=RebinToWorkspace(wsOut,ws,PreserveEvents=True)
print("The values for every 10th bin.")
print("bin\tws\twsOut")
for i in range (0,ws.blocksize(),10):
print("{}\t{:.2f}\t{:.2f}".format(i,ws.readY(0)[i],wsOut.readY(0)[i]))
Output:
The values for every 10th bin.
bin ws wsOut
0 6.00 6.00
10 6.00 6.00
20 6.00 6.00
30 214.00 6.00
