IARG=0-99 ==> called from EGS =0 normal call =1 particle to be discarded because its energy has dropped below the minimum energy threshold (PCUT for photons, ECUT for electrons). =2 nearly the same as 1 =3 particle to be discarded due to USER request. =4 Fluorescent photon to be discarded. (see EGS manual for more details) IARG > 99 ==> called from STEP = 100 dE/dx loss for a normal step of a heavy charged particle, or non dE/dx step for K0 or neutron. = 101 Stopping charged particle. Deposit full energy. = 103 stopping negative particle = 104 energy loss from large angle nuclear scatter = 105 discarded particle = 107 dummy call to afford the user an opportunity to discard a particle before the call to SHOWER (by setting IDISCU=1). = 108 call from PHTNUC for the deposition of nuclear excitation energy. = 109 CALL FROM UMCNINT TO ACCOUNT FOR LOST ENERGY IN NUCLEAR INTERACTION = 110 Load real target K hits from beam file via USTART = 111 Load real target accidental hits from beam file via USTART
EDEP
is the energy deposited for the step under consideration- i.e., the
amount of energy about to be deposited.
STEP
the length of the step about to be taken (in cm).
IRRR
the region index of the step's starting point.
XX,YY,ZZ
the position coordinates at the beginning of the step.
UUU,VVV,WWW
the direction cosines at the beginning of the step.
TIME
is the time at which the energy deposition occurs in ns.
