Gain Notes for Revolution 160
	
JEM-X2: A quite normal revolution with fine gain fitting. All the data from 
this revolution should be useable.
First 2 points on each curve are the partial switch on of the instrument with
HV set 3 steps below its nominal value.
The HV switch off right at the end of the revolution is well fitted and
should not affect the science data. The gain decay seen after the re-activation
is due to charge redistribution on the microstrip plate. Switch off was 
caused by automatic shutdown initiated by the radiation monitor due to high
particle background.

From End-of-revolution report:
c) 2004-02-06T13:59 MOC said: Since 12:44 to 13:59 JemX2 in safe mode due  
    to IREM trigger. Will stay in safe mode until new revolution.

	Gain Notes for Revolution 160

Re-evaluation to check that latest software with temperature dependance, and other
novelties not available when this revolution was last analysed, are still working
well with early revolutions involving autonomous switch offs and other non-standard
behaviour.
	

JEM-X2: 

The Xe line analysis performed using the IC table shows excellent gain
correction with all except the very first science windows having a Xe level 
within 1% of the ideal. As usual however, it is recommended that users
avoid the first few science windows for energy-sensitive applications.
This small scatter of Xe line data during a revolution is typical for early
revolutions and reflects the very small temperature dependance of the gain at
this point in the mission. The new results with OSA9 software are essentially
the same as those for the earlier versions of the softwared.
