Example:2 72 M2 F2 >2 Tis an outgoing body;2 Pis the rest mass ofThe first input data are the reference rigidityƒ wG ‰ G ¬€4¡ ! 1 ! an index IBODY which specifies the particle to be ray-traced, namely M3 (IBODY = 1), M5 (IBODY = 2) or M6 (IBODY= 3). In this last case, initial conditions for M6 must be generated by a first run of OBJETA with IBODY = 2; they arethen stored in a buffer array, and restored as initial conditions at the next occurrence of OBJETA with IBODY = 3. Notethat zgoubi by default assumes positively charged particles. ¥ OAnother index, KOBJ specifies the type of distribution for the initial transverse coordinates , ; namely either uniform(KOBJ = 1) or Gaussian (KOBJ = 2). The other three coordinates , and are deduced from the kinematic of thereactions.The next data are the number of particles to be generated, IMAX , and the masses involved in the two previous reactions.287> 2287and the kinetic energy of the incoming body ( ).Then one gives the central value of the distribution for each coordinate2 T2 P2 M2 Fand the width of the distribution around the central value"+" "‹¥"XOS"v"r"¥I"so that only those particles in the range P P B BQB Owill be retained.

4.3 Declaration of options 43\P4.3 Declaration of optionsThese options allow the control of procedures that affect certain functions of the code. Some options are normally declaredright after the object definition (e.g. SPNTRK - spin tracking, MCDESINT - in-flight decay), others are normally declaredat the end of the data pile (e.g. END – end of a problem, REBELOTE – for tracking more q than ˜particles or formulti-turn tracking, FIT – fitting procedure).
