Gain Notes for Revolution 38 JEM-X1: No scientific data or gain history for this unit. JEM-X2: A quite normal revolution with fine gain fitting. The Xe line analysis confirms the very good gain calibration for this revolution with all the Full Imaging Science Windows having a Xe line position with about 1% of the ideal value. The vast majority of the data in this revolution was taken in Restricted Imaging mode, which is only a partially supported data mode. The last dozen science windows are in Full imaging mode and these are the ones used for the Xe analysis. CAO 12/12/2007
