Gain Notes for Revolution 824 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 excellent, within 1-2% of the ideal. Results shown here use OSA8.0 software and so include temperature variation in the smoothed gain model. 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. CAO 11/08/2009
