Detailed Description

Produce set of event shape variables. The values of different event shape variables are stored as doubles in the event. They can be retrieved with InputTags like "moduleName::instanceName", where moduleName corresponds to "eventShapeVarsProducer" per default and instance name specifies an individual event shape variable which you wish to retrieve from the event:

• thrust
• oblateness
• isotropy
• circularity
• sphericity
• aplanarity
• C
• D

See http://cepa.fnal.gov/psm/simulation/mcgen/lund/pythia_manual/pythia6.3/pythia6301/node213.html ( http://cepa.fnal.gov/psm/simulation/mcgen/lund/pythia_manual/pythia6.3/pythia6301/node214.html ) for an explanation of sphericity, aplanarity and the quantities C and D (thrust and oblateness).
