Gain Notes for Revolution 176 JEM-X1: A quite normal revolution with fine gain smoothing. 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 after the initial switch on. Generally low noise and glitch activity. Some nice clean glitches on source 2 (yellow). CAO 6/12/2005
