<p></p> <p><b>New page</b></p><div>== Intro ==<br /> This page addresses some basic questions in trigger efficiency studies, namely<br /> * Which trigger fired?<br /> * How do I find out which trigger object caused the trigger to fire?<br /> * Which off-line object corresponds to which trigger object (matching)?<br /> <br /> There exist helper tools in athena to answer these questions, the [https://twiki.cern.ch/twiki/bin/viewauth/Atlas/TrigDecisionTool TrigDecisionTool] ([https://svnweb.cern.ch/trac/atlasoff/browser/Trigger/TrigAnalysis/TrigDecisionTool/trunk svn]) and the [https://twiki.cern.ch/twiki/bin/viewauth/Atlas/TriggerObjectsMatching TrigMatchTool] ([https://svnweb.cern.ch/trac/atlasoff/browser/Trigger/TrigAnalysis/TrigObjectMatching/trunk svn]). They can be run on AOD (and ESD, I guess).<br /> Note: This is all very incomplete.<br /> <br /> == Including the tools into your algorithm ==<br /> I included a new algorithm into Trigger/TrigAnalysis/TrigAnalysisExamples. [[Include a new Algorithm]] shows how I&#039;ve done this.</div>
