Gain Notes for Revolution 299 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 3 steps below its nominal setting. The Xe line analysis shows that the gain correction has worked very well for the entire revolution with the exception of the first two science windows. All of this science data is useable, though the first two science windows should be used with care. CAO 16/1/2007
