Gain Notes for Revolution 429 JEM-X1: This is a perfectly normal and well-behaved revolution. The gain fitting has performed without problems, and all the data from this revolution should be useable. The level of glitch activity is low. However, the final verification of the gain correction can first be tested when public data is available, to check where the Xe line falls. JEM-X2: No data or gain history table for this unit. CAO 24/04/2006
