Gain Notes for Revolution 564 JEM-X1: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. The Xe analysis shows that the gain correction is well within acceptable limits, though there is a general tendancy for energies to appear a little too high (1-2%) rather than a little too low. JEM-X2: No scientific data or gain history for this unit. CAO 24/8/2007
