Gain Notes for Revolution 765
	
JEM-X1: A quite normal revolution with okay 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 2-3% of the ideal. 
However, as for all revolutions, the first few science windows should be
avoided in any analysis requiring very good gain determination. To get better
energy determination, with 1-2% of the ideal, you will need to use the
version of j_cor_gain (v8.0) found in OSA8.0 which should be available in
early 2009. This is because of the four-fold increase in gain sensitivity
to temperature during the course of the mission. OSA 8.0 includes temperature
dependent smoothing which takes care of this problem.

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