Gain Notes for Revolution 737 JEM-X1: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. The Xe analysis confirms that the energy determination for this revolution is okay, within about 4% of the ideal. However, as for all revolutions, the first few science windows should be avoided in any analysis requiring very good gain determination. To get the best possible energy correction, this revolution should be processed with OSA8.0 which will be available in early 2009 JEM-X2: No scientific data or gain history data for this unit.
