SignalOverError v1

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
