This repository has working code examples (snippets) on how to access different physics objects in the context of CMSSW software.

Physics Objects Extractor Tool (POET)

Description

The POET repository contains packages that verse instructions and examples on how to extract physics (objects) information and methods or tools needed for processing them. These objects can be: electrons, muons, photons, jets, tracks, etc. Refer to the appropriate branches for the different CMS Open Data epochs :

• master: for Run II (extraction from AOD) CMS open/legacy data. In development.
• 2015MiniAOD1: for Run II (extraction from miniAOD) CMS open/legacy data. In development.
• 2012: for Run I (extraction from AOD format) CMS open/legacy data. Already quite functional but still in development.
• 2011: for Run I (extraction from AOD format) CMS open/legacy data. Currently a placeholder for 2011 data manipulation, which needs a few modifications compared to 2012

Please check out the README in each package for further instructions.
