Detailed Description

The SecVtxInfo class: This class contains information of the secondary vertex fit within the jet.

It is not supposed to be an overly intelligent class with much overhead. The class inherits from IBInfo and can therefor be put into the BJet as additional info to the B-Jet.

Currently available methods to retrieve information:

• distance(): Distance between the reconstructed primary vertex and the fitted secondary vertex. The distance is calculated in three dimensions.
• probability(): The fit probability of the secondary vertex.
• mass(): The reconstructed mass of the secondary vertex.
• mult(): Number of tracks in the secondary vertex.
• secVertexPos(): The fitted vertex and its errors on the position. The return type is Trk::RecVertex.
• infoType(): Returns a enum with the type of information in the class. This is done so that the user directly can typecast from IBInfo to the correct concrete implementation (here: SecVtxInfo).

Methods to fill the class with information:

• setSecVtx: Sets the secondary vertex position, the fit probability and the vector of fitted tracks.
• setMult: Sets the multiplicity of the secondary vertex.
• setMass: Sets the mass of the secondary vertex.
