SignalOverError dialog.

Summary

Replace Y by Y/E for a MatrixWorkspace

Properties

Name Direction Type Default Description
InputWorkspace Input MatrixWorkspace Mandatory The name of the input workspace
OutputWorkspace Output MatrixWorkspace Mandatory The name to use for the output workspace (can be the same as the input one).

Description

Take a MatrixWorkspace as input, and replaces the Y values by Y/E (signal divided by error)

Usage

Example: Taking the derivative of logs

ws = CreateSampleWorkspace("Event")
wsOut = SignalOverError(ws)

print("Values from every 10th bin")
print("bin\tY\tE\tY_New")
for i in range (0,ws.blocksize(),10):
    print("{}\t{:.2f}\t{:.2f}\t{:.2f}".format(i,ws.readY(0)[i],ws.readE(0)[i],wsOut.readY(0)[i]))

Output:

Values from every 10th bin
bin     Y       E       Y_New
0       7.00   2.65    2.65
10      7.00   2.65    2.65
20      7.00   2.65    2.65
30      7.00   2.65    2.65
40      7.00   2.65    2.65
50      257.00 16.03   16.03
60      7.00   2.65    2.65
70      7.00   2.65    2.65
80      7.00   2.65    2.65
90      7.00   2.65    2.65
