b2a60966 | 17 | // Implementation version 1 of algorithm class to construct PHOS track segments |
f035f6ce | 18 | // Track segment for PHOS is list of |
194f9939 | 19 | // EMC RecPoint + (possibly) CPV RecPoint |
a4e98857 | 20 | // To find TrackSegments we do the following: |
21 | // for each EMC RecPoints we look at | |
194f9939 | 22 | // CPV RecPoints in the radious fRcpv. |
a4e98857 | 23 | // If there is such a CPV RecPoint, |
194f9939 | 24 | // we make "Link" it is just indexes of EMC and CPV RecPoint and distance |
a4e98857 | 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. | |
194f9939 | 29 | // If there is no CPV RecPoint we make TrackSegment |
a4e98857 | 30 | // consisting from EMC alone. There is no TrackSegments without EMC RecPoint. |
