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