[G14_run] Lowest beam energy

Hello Franz et al.,

	Dao and I are looking at the g14 gold2 data.  One thing we hadn't 
noticed before is that the photon energy spectrum seems to go from 0.83 
GeV to 2.42 GeV.  Since the beam energy was 2.541 GeV, I thought the 
lowest photon energy would be 20% of this, or 0.51 GeV.  Right now we 
would like to have those events between .51 and .83 GeV.  Is there 
something that we are missing, or is there something about the data that 
killed off those photons?

Reinhard
