Summary

Merge 2 TimeSeries logs in a given Workspace.

Properties

Name Direction Type Default Description
Workspace InOut MatrixWorkspace Mandatory Workspace to have logs merged
LogName1 Input string Mandatory The name of the first log to be merged.
LogName2 Input string Mandatory The name of the second log to be merged.
MergedLogName Input string Mandatory The name of the new log as the result of log 1 being merged with log 2.
ResetLogValue Input boolean False Reset both logs’ values to unity for each one.
LogValue1 Input number 0 Unity value of log 1.
LogValue2 Input number 1 Unity value of log 2.

Description

Two TimeSeriesProperty logs are merged together by the time stamps.

Output

A MatrixWorkspace.

Usage

Example - Merge 2 sample logs with value reset:

Load(Filename=r'HYS_11092_event.nxs',OutputWorkspace='HYS_11092_event')
MergeLogs(Workspace='HYS_11092_event',LogName1='Phase1',LogName2='Phase2',MergedLogName='PhaseM12',ResetLogValue='1',LogValue1='1',LogValue2='2')
ws = mtd["HYS_11092_event"]
newprop = ws.run().getProperty("PhaseM12")
prop1 = ws.run().getProperty("Phase1")
prop2 = ws.run().getProperty("Phase2")

print("Phase 1's size = {}, Phase 2's size = {}, Merged size = {}.".format(prop1.size(), prop2.size(), newprop.size()))
for i in range(5):
    print("Phase1              Time[{}] = {}.".format(i, prop1.nthTime(i)))
for i in range(5):
    print("Phase2              Time[{}] = {}.".format(i, prop2.nthTime(i)))
for i in range(5):
    print("Mixed Phase 1 and 2 Time[{}] = {}.".format(i, newprop.nthTime(i)))

Output:

Phase 1's size = 21, Phase 2's size = 20, Merged size = 41.

Phase1              Time[4] = 2012-08-14T18:56:01.546000137 .

Phase2              Time[4] = 2012-08-14T18:56:04.390000000 .
Mixed Phase 1 and 2 Time[0] = 2012-08-14T18:55:52.390000000 .
Mixed Phase 1 and 2 Time[1] = 2012-08-14T18:55:52.390000000 .
Mixed Phase 1 and 2 Time[2] = 2012-08-14T18:55:52.406000000 .
Mixed Phase 1 and 2 Time[3] = 2012-08-14T18:55:52.406000000 .
Mixed Phase 1 and 2 Time[4] = 2012-08-14T18:55:55.640000000 .
