Gain Notes for Revolution 235 JEM-X1: This is a quite normal revolution with fine gain smoothing and all data from this revolution should be useable. The first 3 data points in each curve are the partial switch-on at the beginning of the revolution where the unit is initially activated with HV set 3 steps below its nominal value. The gain smoothing to source 4 is pulled down somewhat by a spurious outlier that can just be seen on the plots of the Fe-source line positions. However this has no significant affect on the gain calibration of this revolution. CAO 21/11/2005
