Gain Notes for Revolution 466 JEM-X1: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. The Xe line analysis confirms the very good gain determination throughout this revolution. The average Xe line position is at 29.7 keV, considerably better than within 1% of the ideal value. Even the first science windows in the revolution are within about 3% of this value, though it's generally a good idea to leave out these SCWs if a good energy determination is required. JEM-X2: No scientific data or gain history for this unit. CAO 30/8/2007
