Gain Notes for Revolution 897
	
JEM-X1: No scientific data or gain history for this unit.


JEM-X2: A quite normal revolution with fine gain fitting. All the data from 
this revolution should be useable. The Xe line analysis confirms the very
good gain calibration for this revolution with all except the very first Science
Windows having a Xe line position within 1-2% of the ideal value.
As always, however, it is suggested that
users avoid the first few science windows in each revolution since this is
where the instrument warms up and gain variations across the plate settle down.
