Detailed Description

Algorithm for Calorimeter Shower reconstruction starting from a given Axis Direction.

This algorithm builds CaloShower objects starting from CALO hits and a line defining the longitudinal direction. The line can be either a CALO axis or the MC true trajectory. The shower start point is reconstructed by means of a two-thresholds algorithm, currently provided by the Reconstruction::CaloTwoThreshShowerStartingPoint function.

Needed event objects:

name	type	store	required	description
caloGeoParams	CaloGeoParams	globStore		Calorimeter geometrical parameters.
caloClusters	CaloClusters	evStore	if processCalo=false	Calorimeter clusters.
<caloHitsName>	CaloHits	evStore	if processCalo=true	Calorimeter hit collection.
caloAxes	CaloAxes	evStore	if trackAxisType=caloAxis	The CALO axes object.
mcTruth	MCTruth	evStore	if trackAxisType=mcTrack	Montecarlo truth.
tracks3D	std::vector<Track>	evStore	if trackAxisType=track	Track from subdetectors tracking algorithms.

Produced event objects:

name	-type-	alias	store	description
caloShowers{MC,CA}(_Inv)	CaloShowers	caloShowers	evStore	The collection of CaloShower objects.

Parameters:

name	type	default value	description
processCalo	bool	false	If true, neglect CaloClusters and process the collection of CaloHits of the whole Calo
edepThreshold	float	0.020	Energy deposit threshold (in GeV) for CaloHits to enter the reconstruction algorithm
caloHitsName	string	caloHitsGeV	Name of the CaloHits collection used for reconstruction. Possible suggested solutions are: caloHitsGeV; caloHitsGGS.
trackAxisType	string	caloAxis	Type of existing track used for Shower reconstruction. Possible values are: caloAxis; mcTrack; track3D
axisInversion	bool	false	If true, the versus of the track used for Shower reconstruction is inverted
