Issue I471 [80,fly2,enhancement,resolved] New FLY2 particle definition format. SIMION 8.0.0 supports a new FLY2 particle definition format that supplants the FLY format of SIMION 7.0. The FLY2 format is a text file (that can be built from the GUI or by hand) and supports substantially greater flexibility in beam definition. See Appendix K "FLY2 Particle Definition Format" of the SIMION 8.0 manual for details. See also http://www.simion.com/info/Particle_Initial_Conditions . Implemented in 8.0.0.
