-class AliITSdigit: public AliDigit {
-////////////////////////////////////////////////////////////////////////
-// Version: 0
-// Written by Rene Brun, Federico Carminati, and Roberto Barbera
-// Minor modifications made and documented by Bjorn S. Nilsen
-// July 11 1999
-//
-// The default ITS digit structure. This should either be replaced
-// or added on to later with the proper digit structure defined for
-// each detector type. See the proposed Digit structure defined by
-// Bjorn S. Nilsen for an example.
-//
-// Data members:
-//
-// Int_t fTracks[3]
-// See AliDigit for a full description. The track numbers, up to 3,
-// that make up this digit.
-//
-// Int_t fEvent
-// The event number for this digit. This information is probably
-// kept someplace else already (via the TTree structure already in use).
-//
-// Int_t fLayer
-// The layer number of this digit. This is part of the information
-// that determines the detector where this digit is located (layer, ladder,
-// and detector numbers).
-//
-// Int_t fLadder
-// The ladder number of this digit. This is part of the information
-// that determines the detector where this digit is located (layer, ladder,
-// and detector numbers).
-//
-// Int_t fDet
-// The detector number of this digit. This is part of the information
-// that determines the detector where this digit is located (layer, ladder,
-// and detector numbers).
-//
-// Int_t fNoverl
-// The number of hits that make up this digit.
-//
-// Member functions:
-//
-// int *GetTracks()
-// See AliDigit for a full description. Returns a pointer to the
-// array fTracks where the tracks number of the tracks that make up
-// this digit are stored.
-//
-// AliITSdigit()
-// The default creator for the AliITSdigit class.
-//
-// AliITSdigit(Int_t *tracks, Int_t *digits)
-// The creator for the AliITSdigit class. This routine fills the
-// AliITSdigit data members from the array digits. The array of track
-// numbers are passed to the AliDigit creator. The order of the elements
-// in the digits array are fEvent = digits[0], fLayer = digits[1],
-// fLadder = digits[2], fDet = digits[3], and fNoverl = digits[4].
-// Therefore the array digits is expected to be at least 5 elements long.
-//
-// ~AliITSdigit()
-// The destructor for the AliITSdigit class. At present the default
-// destructor is used.
