Gain Notes for Revolution 444 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. Large glitches are visible on source 1 (black/red) and source 4 (purple/orange). None of these glitches in any significant way affect the gain smoothing and the gain correction of the science data. JEM-X2: No data or gain history table for this unit. CAO 6/06/2006
