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".
