Java Analysis Studio and the hep.lcd classes Tony Johnson FNAL - LCD workshop - February 1999

Java Analysis Studio Experiment independent Physics Analysis Tool JAS Presentation at FNAL on Wednesday (no time now) Is being used by several people for LCD analysis hep.lcd classes make this possible (subject of this talk]

What is hep.lcd ? hep.lcd a Java framework for Analysis of LCD data from Stdhep, Gismo, Root FASTMC Development of Reconstruction (Clustering and Track Finding) Analysis algorithms Fast Parameterized FASTMC Event Display, Analysis Tools (Jet Finder etc.] Can be used inside JAS or standalone

What is hep.lcd Why Java? More appropriate language than C++ for data analysis Easy to learn Simpler to use Designed as interpretive language Fast Huge industry support Runs on all machines of interest to hep

How does it interface to Gismo? ROOT FastMC StdHEP GISMO Ascii file Detector Description hep.lcd classes Fast MC Recon Analysis Event Display

What’s New Since December Handles new detector geometry files Event Display improved Jet Finding added to Event Shape utilities Bug fixes and improvements New Tutorial + User’s Guide on Web

Users Guide + Tutorial Based on December’s hands-on tutorial Covers all components of hep.lcd package Doesn’t assume any previous experience with Java or Java Analysis Studio Constantly Evolving Document (80% complete) User Feedback Encouraged Every page has a feedback form which sends e-mail to maintainer You can see comments of others plus replies http://www-sldnt.slac.stanford.edu/jas/Documentation/lcd

What’s Next Document FASTMC Merge in updated track finding/fitting package Release version 1.0

Conclusion Hep.lcd + JAS = Events are being generated, but: easy way to get started doing LCD analysis Events are being generated, but: Little time has so far been spent looking at data Even if you don’t have much time please look at data: Does output data make sense? Does it contain what you will need for your analysis? Send feedback to lcd-sim@slac.stanford.edu
