79  197     // Z, A of the colliding ions (symmetric collisions are assumed)
100     // gamma for the colliding ions
4.0 -1 50   // maximum and minimum values for w (the gamma-gamma center of mass
energy, w = 4(E1)(E2), (a -1 tells STARlight to use the default values
specified in setConst.f; otherwise, specific wmin here, and the number
        of w bins in the lookup tables
3.0 30 // maximum value for y (y is the rapidity, y = 0.5 ln(E1/E2) ) and the 
        number of y-bins in the cross section calculation 
1 // gg or gP switch -- A 1 here will produce 2-photon channels, a
// 2 here will produce vector meson channels with a narrow
//resonance, and a 3 here will produce vector meson channels with
//a wide (Breit-Wigner) resonance.
10000 // number of events to produce
331 // channel of interest (in PDG notation); currently supported
options listed below
345738 // random number seed
2 // The form of the output.  A 1 here generates a simple text file.  
        '2' generates a text file in the gstar format
        '3' generates a PAW ntuple.
1 // This number controls the nuclear breakup
        // Note that this option only works for lead or gold; it should work at 
any energy
1 = hard sphere nuclei (b>2R)
2 = both nuclei break up (XnXn)
3 = a single neutron from each nucleus (1n1n)
4 = require that neither nucleon break up (with b>2R)
5 = require that there be no hadronic break up
(This is similar to option 1, but with the actual hadronic interaction
probability)
1       0 = no interference (i.e. turned off), 1= interference turned on0.5     when interference is turned on, this gives the %age interference 0= 
   none, 1=full
0.24.   when interference is turned on, this is the maximum pt considered
120     when interference is turned on, this is the number of pt bins
