Gain Notes for Revolution 101 JEM-X1: No scientific data or gain history for this unit. JEM-X2: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. First few points on each curve belong to the partial switch-on for which HV is set 3 steps below its nominal value. The Xenon line analysis on the available public data shows that the gain correction has worked very well, at least for the last SCWs in the revolution, which is to be expected. CAO 18/12/2006
