RIO_Author

using Muon::IMMClusterBuilderTool::RIO_Author = MMClusterOnTrack::Author

inherited

Refinement of the cluster position after the cluster calibration loop is ran with a complete external constraint (e.g.

from the track fit). The cluster local position and the associated covariance are updated during this procedure Returns the Author of the ClusterBuilderTool, in case that the calibrated strip passes all internal constraints of the ClusterBuilder, otherwise Unknown author is returned. In the latter case, the Cluster should not be transformed into a calibrated RIO object.

Parameters

ctx	EventContext used for StoreGate access
calibratedStrips	Cluster constitutents after the calibration stage
directionEstimate	Estimate of the direction given in the local frame
clusterLocalPosition	Vector to which the final cluster position is saved to
covMatrix	Uncertainty associated with the local position
