19 | // Reconstructed space point class for set:ITS | |
20 | // Reconstructed points are expressed simultaneously in two different | |
21 | // reference frames, both differing from the global system. | |
22 | // The first is referred to the sensor (see AliITSsegmentation for the | |
23 | // definition) and each point is represented by two coordinates: fXloc and | |
24 | // fZloc. This system in the code is referred to as "local" | |
25 | // The second is used for tracking (V2, SA and MI versions) and the X axis | |
26 | // represents the radial coordinate (this system is, in the bending plane, | |
27 | // a rotated system w.r.t. the global reference system). | |
28 | // Each reaconstructed point is represented by two coordinates: fY and fZ, | |
29 | // inherited from AliCluster. This system in the code is referred to as | |
30 | // "trackingV2". | |
