Gain Notes for Revolution 305 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 quite well, though for many science windows the deviation from ideal gain determination is about 1-2%. Users should bear this in mind when using this data. CAO 16/1/2007
