Gain Notes for Revolution 804
	
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  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. Results shown
here use OSA8.0 software and so include temperature variation in the
smoothed gain model in the Xe line determination. However due to lack of
OSM housekeeping in the NRT repository at the time of gain smoothing analysis
the individual fits to the calibration spectra are done with OSA7.2 software. 

Calibration source number 4 (purple/orange) is no longer
used for calibration purposes since an anode strip directly under the source
has broken and no useable signal comes from this area of the detector any
longer.

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