Gain Notes for Revolution 918
	
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 okay
gain calibration for this revolution with all the Science
Windows having a Xe line position with about 3% 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.
