b2a60966 17// Implementation version 1 of algorithm class to construct PHOS track segments
f035f6ce 18// Track segment for PHOS is list of
19// EMC RecPoint + (possibly) CPV RecPoint + (possibly) PPSD RecPoint
a4e98857 20// To find TrackSegments we do the following:
21// for each EMC RecPoints we look at
22// CPV/PPSD RecPoints in the radious fR0.
23// If there is such a CPV RecPoint,
24// we make "Link" it is just indexes of EMC and CPV/PPSD RecPoint and distance
25// between them in the PHOS plane.
26// Then we sort "Links" and starting from the
27// least "Link" pointing to the unassined EMC and CPV RecPoints assing them to
28// new TrackSegment.
29// If there is no CPV/PPSD RecPoint we make TrackSegment
30// consisting from EMC alone. There is no TrackSegments without EMC RecPoint.
f035f6ce 31//
32// In principle this class should be called from AliPHOSReconstructioner, but
a4e98857 33// one can use it as well in standalone mode.
34// Use case:
fc12304f 35// root [0] AliPHOSTrackSegmentMakerv1 * t = new AliPHOSTrackSegmentMaker("galice.root", "tracksegmentsname", "recpointsname")
a4e98857 36// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
fc12304f 37// // reads gAlice from header file "galice.root", uses recpoints stored in the branch names "recpointsname" (default = "Default")
38// // and saves recpoints in branch named "tracksegmentsname" (default = "recpointsname")
a4e98857 39// root [1] t->ExecuteTask()
40// root [2] t->SetMaxEmcPpsdDistance(5)
41// root [3] t->SetTrackSegmentsBranch("max distance 5 cm")
42// root [4] t->ExecuteTask("deb all time")
