Analysis Object Data (AOD)
AOD is the end user, physicist data. AODs are obtained by filtering ESDs (tracks, vertices, ...) or by high level reconstruction based on ESDs or AODs (charmed hadrons, jets, photons, ...).
The design of the AOD in AliRoot is equal to the one for ESD. The persistent data consists of branches of a tree (treeAOD). A transient class AliAODEvent is responsible to create and connect standard AOD data to the tree. New AOD data objects can be added dynamically.
Requirements from ALICE Physics Working Groups (PWGs)
The contents of the AOD data classes has been discussed in several analysis sessions during recent offline weeks.
" Status of the AOD", M. Oldenburg Offline Week, October 2007, files
In a common meeting of the conveners and interested members of the ALICE Physics Working Groups organized by the Physics Coordinator we agreed on the design of the standard AOD classes.
The implementation of the AOD classes are coordinated by Andreas Morsch (Andreas.Morsch AT cern.ch).
Some open issues:
- Detector PID information for high-p T particles in AliAODTrack (contact A. Mastroserio)
- Charmed hadron reconstruction based on AOD input (contact A. Dainese)
