Gain Notes for Revolution 783
	
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 3% of the ideal. 
However, 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. This is the
first full revolution after the loss of the fourth calibration source, but
this is no longer a problem since the science data is now corrected without
the use of this source.

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