		JEventLoop *	loop
	)

For photon reconstruction, we just check if the total energy in ether the BCAL or FCAL is greater than 50% of the thrown value to determine if it is reconstructible.

This is not entirely accurate since a photon could convert upstream and spray that much energy into a calorimeter and the photon would then not be reconstructible.

On the other hand, if you are really looking for detection efficiency, then you'll want that to be included in the calculation so maybe this is a good thing ....?
