Gain Notes for Revolution 724
	
JEM-X1: A quite normal revolution with fine gain fitting. All the data from 
this revolution should be useable. The Xe analysis confirms that the energy
determination for this revolution is okay, within about 2% of the ideal. 
However, the general level of the Xe line appears to be quite low. This may
have to do with the fact that the gain of the instrument is currently very
high and this puts the Xe peak on a sharp falloff at high energy that surpresses
the peak on its high side and hence pushes the position of the peak to lower
energies. If this is the case, no correction for this low Xe line needs to
be performed since all the lower energy photons will still have been corrected
to their proper value. Also, this revolution might benefit from using the
newer OSA8.0 software that will be available in 2009.

JEM-X2: No scientific data or gain history data for this unit.
