Reaction 1 has been used as a benchmark to examine both acceptance and kaon identification in the detector. Events have been generated according to phase-space with a t-dependence given as exp(-alpha|t|) with a slope parameter, alpha=5.
The resonance X has been taken with a width T=0.150GeV decaying into K+1(1270)K-. Equal numbers of events for mX of 1.7 GeV/c2, 2.5GeV/c2 and 3.2GeV/c2 have been produced for photon beam energies of 8, 10 and 12 GeV, while for 6GeV, only the 1.7 GeV/c2 and 2.5GeV/c2 masses have been generated.
