Gain Notes for Revolution 439 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. A large multiple glitch can be seen on source 1 (black/red) towards the beginning of the revolution. This feature is composed of 4 separate glitches, but does not affect the gain smoothing or gain correction of the science data. JEM-X2: No data or gain history table for this unit. CAO 29/05/2006
