699C GET BU(NCH) S(IZE)
700C
701C CALCULATES OPTIMAL BUNCH SIZE FOR CERENKOV PHOTONS. CERENKOV PHOTONS
702C ARE GROUPED IN BUNCHES IN ORDER TO ACCELERATE COMPUTING TIME.
703C HOWEVER, WE SET A MAXIMAL VALUE FOR THE GROUPING OF CERENKOV PHOTONS
704C SO THAT WE GET AT LEAST 100 BUNCHES/M**2 AT A CERENKOV FLUX OF 3000
705C PHOTONS/M**2. THIS IS THE MINIMUM CERENKOV FLUX WHICH CAN BE
706C DISTINGUISHED FROM THE NIGHT SKY LIGHT BACKGROUND IN THE HEGRA
707C EXPERIMENT AT THE ISLAND LA PALMA. SO THE PARAMETRIZATION OF THE
708C CERENKOV BUNCH AS CALCULATED IN THIS SUBROUTINE IS VALID FOR
709C OBSERVATION LEVELS SIMILAR TO THAT OF THE HEGRA EXPERIMENT.
710C FOR A GIVEN PRIMARY PARTICLE, INCIDENT ENERGY AND ANGLE, AN
711C OPTIMAL BUNCH SIZE IS CALCULATED BY INTERPOLATION IN A TABLE,
712C WHERE WE HAVE CHOSEN AN ENERGY RANGE UP TO 1000 TEV, INCIDENT
713C ANGLES 0 AND 40 DEGREES, AND 4 TYPES OF PRIMARIS: GAMMAS,
714C PROTONS, NITROGEN, AND IRON.
715C THIS SUBROUTINE IS CALLED FROM MAIN
716C ARGUMENTS:
717C IPARTI = TYPE OF PRIMARY PARTICLE
718C ENERGY (R4) = PARTICLES ENERGY IN GEV
719C THETA (R4) = ANGLE IN RAD
