Gain Notes for Revolution 202 JEM-X1: A quite normal revolution with fine gain smoothing that is interrupted by a short, unscheduled switch off. All data from this revolution should be useable. The first few points in each curve are from the partial switch-on at the beginning of the revolution, for which HV is set 3 steps below its nominal value. All sources show clear fast relaxation due to charging of the plate. This causes a rapid gain decay both after initial switch on, and after reactivation. However, both decays are well fitted, and this break should in no way affect the quality of the data. CAO 5/12/2005
