= format of the output files : lumi.eg.out, lumi.ge.out and lumi.gg.out = the data are in ASCII : 1. energy of the colliding particle coming from the beam 1 (GeV) 2. energy of the colliding particle coming from the beam 2 (GeV) 3. x position of the collision within the bunch (nm) 4. y position of the collision within the bunch (nm) 5. z position of the collision (micrometers) 6. label before output, the data are randomized. The label (6th data) reflects the primitive order provided by the guineapig++ calculation. Remark : the label (and therefore randomization) is available only from version 1.0.0 on.
