Detailed Description

A concrete implementation of IInDetBeamSpotTool, using primary vertex information to determine the position of the beamspot using a chi2 and/or log-likelihood method.

Abstract class for all beamspot determination algorithms. Any class for finding the position of the beamspot needs to derive itself from this class.

Declare a new Gaudi property.
