Gain Notes for Revolution 609
	
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 good, 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. 

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