Gain Notes for Revolution 258 JEM-X1: A quite normal revolution with fine gain smoothing. All data from this revolution should be useable. The first two points of each data set are the partial switch-on with the High Voltage 3 steps below its nominal value. Good example of a broad glitch on source 4, that is a glitch that's followed by a couple of others that suppress the gain for a longer period of time than a single glitch. CAO 18/11/2005
