Query: Calculations of neutrino spectra with a program based on the GEANT
  library   The methods of neutrino spectra calculations with GEANT library and the
peculiarities of such calculations for different neutrino beams are summarized.
The formula expressing $K^0$ yields from a neutrino target through the $K^+$
and $K^-$ yields from the same target is proposed
