Gain Notes for Revolution 582 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 about 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. Since the temperature variation of the gain has doubled 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 data for this unit. CAO 31/8/2007
