Gain Notes for Revolution 142 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 are the partial switch on of the instrument with HV set 3 steps below its nominal value. The short switch off of the unit towards the beginning of the revolution is well-fitted by the gain smoothing program, so there should be no affect on the science data around this time. CAO 16/01/2006
