74// Implementation version 1 of algorithm class to construct PHOS track segments
75// Track segment for PHOS is list of
76// EMC RecPoint + (possibly) CPV RecPoint
77// To find TrackSegments we do the following:
78// for each EMC RecPoints we look at
79// CPV RecPoints in the radious fRcpv.
80// If there is such a CPV RecPoint,
81// we make "Link" it is just indexes of EMC and CPV RecPoint and distance
82// between them in the PHOS plane.
83// Then we sort "Links" and starting from the
84// least "Link" pointing to the unassined EMC and CPV RecPoints assing them to
85// new TrackSegment.
86// If there is no CPV RecPoint we make TrackSegment
87// consisting from EMC alone. There is no TrackSegments without EMC RecPoint.
88//// In principle this class should be called from AliPHOSReconstructor, but
89// one can use it as well in standalone mode.
90// Use case:
91// root [0] AliPHOSTrackSegmentMakerv1 * t = new AliPHOSTrackSegmentMaker("galice.root", "tracksegmentsname", "recpointsname")
92// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
93// // reads gAlice from header file "galice.root", uses recpoints stored in the branch names "recpointsname" (default = "Default")
94// // and saves recpoints in branch named "tracksegmentsname" (default = "recpointsname")
95// root [1] t->ExecuteTask()
96// root [3] t->SetTrackSegmentsBranch("max distance 5 cm")
97// root [4] t->ExecuteTask("deb all time")
