Gain Notes for Revolution 160 JEM-X2: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. First 2 points on each curve are the partial switch on of the instrument with HV set 3 steps below its nominal value. The HV switch off right at the end of the revolution is well fitted and should not affect the science data. The gain decay seen after the re-activation is due to charge redistribution on the microstrip plate. Switch off was caused by automatic shutdown initiated by the radiation monitor due to high particle background. From End-of-revolution report: c) 2004-02-06T13:59 MOC said: Since 12:44 to 13:59 JemX2 in safe mode due to IREM trigger. Will stay in safe mode until new revolution. CAO 10/01/2006
