  This table provides the user with a possibility to choose distributions,
which will be filled during the Monte Carlo sessions.
  The tested value must be described in the first column. It is defined by
a key character and a particle set following this character. For example, 
"C13" means cosine of angle between the first and the third particles.
  The following key characters are available:
  A  - Angle  in degree unit
  C  - Cosine of angle   
  J  - Jet cone angle    
  E  - Energy of the particle set
  M  - Mass of the particle set 
  P  - Cosine in the rest frame of particles. 
  T  - Transverse momentum P_t  of the particle set 
  S  - Squared mass
  Y  - Rapidity of particle set.
  U  - user defined function 
See Manual for details.
  The second and the third columns are used to define a range of the
distribution. 
  For the C-version of CompHEP the ranges may be described by an algebraic
formula which contains numbers and CompHEP identifiers.
   For the  Fortran realization only numbers are permitted into these 
fields. To define ranges  of 'S'-type variable the user must input 
GeV units value V which will be transformed to V*abs(V).
