Gain Notes for Revolution 520
	
JEM-X1: A quite normal revolution with fine gain fitting. All the data from 
this revolution should be useable. However, the smoothing model is a little
too stiff to accomodate the temperature changes during the revolution, and we
can expect a regular deviation of the gain correction from the ideal corrections
where the smoothing does not quite follow the gain history. The Xe line analysis
confirms that there is a strong residual temperature signal in the Xe position
for this revolution, though the energy correction is within 2-3% of the ideal
for most of the revolution.
Since the temperature variation of the gain has tripled since the beginning of 
the mission, future offline calibrations, including temperature dependency, 
could possibly benefit this revolution when they become available in the coming
year.


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