Detailed Description

class AreaSeededTrackingRegionsProducer

eta-phi TrackingRegions producer in directions defined by z-phi area-based objects of interest from the "input" parameters.

Four operational modes are supported ("mode" parameter):

BeamSpotFixed: origin is defined by the beam spot z-half-length is defined by a fixed zErrorBeamSpot parameter BeamSpotSigma: origin is defined by the beam spot z-half-length is defined by nSigmaZBeamSpot * beamSpot.sigmaZ VerticesFixed: origins are defined by vertices from VertexCollection (use maximum MaxNVertices of them) z-half-length is defined by a fixed zErrorVertex parameter VerticesSigma: origins are defined by vertices from VertexCollection (use maximum MaxNVertices of them) z-half-length is defined by nSigmaZVertex * vetex.zError

If, while using one of the "Vertices" modes, there's no vertices in an event, we fall back into either BeamSpotSigma or BeamSpotFixed mode, depending on the positiveness of nSigmaZBeamSpot.
