class AliITSRecPoint: public AliCluster

  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".
