===Results of the simulation===
All results from this simulation are stored on the UConn srm. They are available on the UConn cluster in the nfs mounted directory /pnfs/phys.uconn.edu/data/Gluex/radphi/omega_sim-6-2014 or remotely at the srm://grinch.phys.uconn.edu/Gluex/radphi/omega_sim-6-2014 url. Files in this directory are either raw simulation output or reconstructed simulation results in the form of root trees. Files of the former type have the .itape extension and those of the latter type have the .root extension. The file names indicate the simulated channel, as given in the list below.
The events below were generated using a slope parameter of 8.0/GeV<sup>2</sup>. These data files are stored in the group dcache area under /pnfs/phys.uconn.edu/data/Gluex/radphi/omega_sim-6-2014.

===Results of the simulation===
===Monte Carlo Events with Slope Parameter b=5.5/GeV<sup>2</sup>===
Monte Carlo events are generated with a new slope parameter of 5.5/GeV<sup>2</sup>. The previous results (shown above) were generated using a slope parameter of 8.0.
* γ p -> (Δ<sup>+</sup> -> p π<sup>0</sup>) (ω -> π<sup>0</sup>γ)
10<sup>8</sup> events are generated and then simulated in the detector.
To make this change edit the file decay.dat for each reaction of interest. Then the generation and simulation proceed as before.
These data files are stored in the group dcache area under /pnfs/phys.uconn.edu/data/Gluex/radphi/omega_sim-6-2014.
