1. Testing Physics Examine at D0 FNAL/Univ. of Illinois Soojin Kwon Advisor: Pushpa Bhat (FNAL) 3 July 2002

2. Physics Examine Developed by Michiel Sanders The goal is to monitor the data quality of physics runs Runs Reco + RecoAnalyze online in the Examine framework and produces “RecoAnalyze.root” A root script then produces histograms in “PhysicsExamine.root” from “RecoAnalyze.root” The current version is based on p11.07.00
