Detailed Description

File: TrigElectron.h.

Description: To be created by FEX algorithms in Level 2 chains. Encodes electron candidate. Should contain parameters that are used for cuts in L2 and point to original objects (track and EM cluster) so that the latter can be separated off for EDM slimming.

Design: Must be light and easy to serialize AND to store in ESD/AOD; since pointers don't work (copied by POOL), use ElementLinks instead (now – May 08 – being made serializable)

The idea is that the variables used for cuts should be kept in the TrigElectron class for redundancy. The remaining quantities, not used for cuts, are accessible from the ElementLinks to TrigEMCluster and TrigInDetTrack. This allows for EDM slimming (or thinning, whatever, removing unnecessary information) by not storing the cluster and track.

In practice, some calorimeter variables would have to be recalculated from the actual variables stored in TrigEMCluster. To avoid the time overhead, the original variables are copied.

Authour: R.Goncalo - Tue Sep 20 22:02:43 BST 2005

Modified: RG Mar 8 2006: replaced EMShowerMinimal with TrigEMCluster RG Mar 20 2006: added bool m_valid for hypos to validate elec. RG Nov 7 2006: to inherit from INav4M and 4-mom base RG May 22 2008: ElementLinks to track and cluster; change data members RG Apr 07 2009: add comparison and << operators RG May 18 2009: add TRT variables; remove obsolete validate() accessor RG Jun 22 2009: add some calorimeter vars. changed TRT accessor names

		float	EToverPT,
		const TrigEMClusterContainer *	cluster,
		unsigned int	cl_index,
		const TrigInDetTrackCollection *	track,
		unsigned int	tr_index )

constructor used to initialize TrigElectrons (there are no "set()" methods)

Constructor: Faster to pass TrigEMClusterContainer and TrigInDetTrackCollection pointers and indices to track and cluster, so that ElementLinks to track and EM cluster can be initialized quickly
Design choice: pass data member values as constructor parameters, rather than providing accessors to update these values later; 4-momentum variables can still be updated through the P4PtEtaPhiM maseclass accessors.

Set data members from tracking and calorimeter quantities. The idea is that the variables used for cuts should be kept in the TrigElectron class for redundancy. The remaining quantities, not used for cuts, are accessible from the ElementLinks to TrigEMCluster and TrigInDetTrack. This allows for EDM slimming (or thinning, whatever, removing unnecessary information) by not storing the cluster and track. In practice, some calorimeter variables would have to be recalculated from the actual variables stored in TrigEMCluster. To avoid the time overhead, the original variables are copied.

Set ElementLinks to TrigEMCluster and TriginDetTrack: use fast method with reference to collection + index (O(1)), instead of reference to track (O(n) for n elements in collection). Notes:

1. the cluster container is held by steering; track container is per RoI
2. if e-links not valid, just set data member links to default value
   

set data members from track quantities

Initialize 4-momentum base-class angular quantities from track data: assume that track parameters at perigee give better estimates of angular quantities near vertex
