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: | |
35 | // root [0] AliPHOSTrackSegmentMakerv1 * t = new AliPHOSTrackSegmentMaker("galice.root") | |
36 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
37 | // root [1] t->ExecuteTask() | |
38 | // root [2] t->SetMaxEmcPpsdDistance(5) | |
39 | // root [3] t->SetTrackSegmentsBranch("max distance 5 cm") | |
40 | // root [4] t->ExecuteTask("deb all time") | |
