Gain Notes for Revolution 731
	
JEM-X1: A quite normal revolution with okay gain fitting. All the data from 
this revolution should be useable. The Xe analysis shows that the energy
determination for this revolution is not so good, within about 4-5% of the ideal. 
As for all revolutions, the first few science windows should be
avoided in any analysis requiring very good gain determination. Since the
temperature variation of the gain has tripled since the beginning of the
mission, future version of OSA (version 8.0), including temperature dependency,
will benefit this revolution when it becomes available in 2009. New calibration
reference channels need to be determined for the revolutions since 713, so
be sure to use the newest IMOD package when you process these revolutions.

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