Detailed Description

Select events based on a user defined cut.

If .Tag is specified, events are tagged, otherwise events are rejected, if they don't fulfill the selection criteria.

The cut follows the usual TTree::Draw() rules, e.g. "Muon.pT() > 10.0 && abs(Muon.eta()) < 2.0"

Configuration options:

• .Select: Expression [default:"1"]
• .Tag: String [default: ""]
• .Variables: StringList [ default: empty ]

The .Variables: entry should be only used for optimization. During the execution of the selection only the designated branches are enabled for reading. For example, if you use only EMscone.Pt() in your expression, and you know that it uses only EMscone.fX and EMscone.fY, you can mention these in the .Variables: configuration entry.
