24 | // Implementation version 2 of algorithm class to construct PHOS track segments | |
25 | // Track segment for PHOS is list of | |
26 | // EMC RecPoint + (possibly) projection of TPC track | |
27 | // To find TrackSegments we do the following: | |
28 | // for each EMC RecPoints we look at | |
29 | // TPC projections radius fRtpc. | |
30 | // If there is such a track | |
31 | // we make "Link" it is just indexes of EMC and TPC track and distance | |
32 | // between them in the PHOS plane. | |
33 | // Then we sort "Links" and starting from the | |
34 | // least "Link" pointing to the unassined EMC and TPC assing them to | |
35 | // new TrackSegment. | |
36 | // If there is no TPC track we make TrackSegment | |
37 | // consisting from EMC alone. There is no TrackSegments without EMC RecPoint. | |
38 | //// In principle this class should be called from AliPHOSReconstructor, but | |
39 | // one can use it as well in standalone mode. | |
40 | // Use case: | |
41 | // root [0] AliPHOSTrackSegmentMakerv2 * t = new AliPHOSTrackSegmentMaker("galice.root", "tracksegmentsname", "recpointsname") | |
42 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
43 | // // reads gAlice from header file "galice.root", uses recpoints stored in the branch names "recpointsname" (default = "Default") | |
44 | // // and saves recpoints in branch named "tracksegmentsname" (default = "recpointsname") | |
45 | // root [1] t->ExecuteTask() | |
46 | // root [3] t->SetTrackSegmentsBranch("max distance 5 cm") | |
47 | // root [4] t->ExecuteTask("deb all time") | |
