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