Gain Notes for Revolution 494
	
JEM-X1: A quite normal revolution with fine gain fitting. All the data from 
this revolution should be useable. The very strong rise in gain at the beginning
of the revolution shows the effect of warming the satellite after it comes out
of eclipse during the perigee passage.
The Xe line analysis demonstrates that the gain correction has performed
well, to within about 2% of the ideal. As always it is recommended that
users avoid the first few science windows for applications requiring the very
best spectral/energy information since this is where the unit is settling down
after the switch on.

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