Gain Notes for Revolution 548 JEM-X1: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. Final confirmation of the goodness of the gain calibration must be confirmed by a Xe analysis of the entire revolution. A big glitch is visible on source 1 (black/red), but this is well smoothed by the gain correction program and in no way affects the science data. JEM-X2: No scientific data or gain history for this unit. CAO 30/04/2007
