Gain Notes for Revolution 710 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, OSA releases after version 7.0 could possibly improve the stability of the gain correction JEM-X2: No scientific data or gain history data for this unit.
