// Implementation version 1 of algorithm class to construct PHOS track segments
// Track segment for PHOS is list of
-// EMC RecPoint + (possibly) CPV RecPoint + (possibly) PPSD RecPoint
+// EMC RecPoint + (possibly) CPV RecPoint
// To find TrackSegments we do the following:
// for each EMC RecPoints we look at
-// CPV/PPSD RecPoints in the radious fRcpv.
+// CPV RecPoints in the radious fRcpv.
// If there is such a CPV RecPoint,
-// we make "Link" it is just indexes of EMC and CPV/PPSD RecPoint and distance
+// we make "Link" it is just indexes of EMC and CPV RecPoint and distance
// between them in the PHOS plane.
// Then we sort "Links" and starting from the
// least "Link" pointing to the unassined EMC and CPV RecPoints assing them to
// new TrackSegment.
-// If there is no CPV/PPSD RecPoint we make TrackSegment
+// If there is no CPV RecPoint we make TrackSegment
// consisting from EMC alone. There is no TrackSegments without EMC RecPoint.
-//// In principle this class should be called from AliPHOSReconstructioner, but
+//// In principle this class should be called from AliPHOSReconstructor, but
// one can use it as well in standalone mode.
// Use case:
// root [0] AliPHOSTrackSegmentMakerv1 * t = new AliPHOSTrackSegmentMaker("galice.root", "tracksegmentsname", "recpointsname")
// // reads gAlice from header file "galice.root", uses recpoints stored in the branch names "recpointsname" (default = "Default")
// // and saves recpoints in branch named "tracksegmentsname" (default = "recpointsname")
// root [1] t->ExecuteTask()
-// root [2] t->SetMaxEmcPpsdDistance(5)
// root [3] t->SetTrackSegmentsBranch("max distance 5 cm")
// root [4] t->ExecuteTask("deb all time")
//
