Gain Notes for Revolution 712 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% 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 tripled since the beginning of the mission, future versions of OSA software (higher than 7.0) will automatically provide this temperature dependence, and may possibly improve the energy correction stability even further. JEM-X2: No scientific data or gain history data for this unit. CAO 27/10/2008
