Gain Notes for Revolution 304 A completely ordinary revolution. Gain smoothing is fine. All data from this revolution should be useable. First two points in data set are pre-switch on of High Voltage at three steps below its nominal setting. The Xe line analysis shows that the gain correction has worked perfectly for the entire revolution. The first few science windows deviate from the ideal correction by 1-2%, and should be treated a little cautiously. Otherwise all of this science data can be used without problems. CAO 16/1/2007
