Gain Notes for Revolution 709 JEM-X1: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. The Xe analysis shows that despite some signs of poor gain smoothing, the corrected data is with about 2% of the ideal value, though using software later than OSA7.0 could possibly improve on this. JEM-X2: No scientific data or gain history data for this unit. CAO 27/10/2008
