Pico V0 package

• Package for V0-jet analysis in pp, p-Pb/Pb-p and Pb-Pb

output objects in delta AOD

Utils

• AliPicoBase: nanespace for constants, such as the V0 mass, which will be used in the analysis

Event level info

• AliPicoHeaderV0: delta AOD header which strores event level info (eg. vtx, EP, trg...)
• AliPicoHeaderJE: AliPicoHeaderV0 + jet background density

V0 info

• AliPicoV0: basic class which stores V0 info
• AliPicoV0RD: AliPicoV0 + info used for data analysis
• AliPicoV0MC: AliPicoV0 + info used for MC analysis

Jet info

• AliPicoJet: stores info of jet kinematics, area and leading particle pT
