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. Choose the appropriate branch for a given CMS Open Data epochs/format. Currently, these are:
master: for Run II (extraction from AOD) CMS open/legacy data. In development.2015MiniAOD: 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.
