Gain Notes for Revolution 43 JEM-X1: No scientific data or gain history for this unit. JEM-X2: 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. First few points on each curve belong to the partial switch-on for which HV is set 3 steps below its nominal value. A very big glitch is visible on ( ), but this is well smoothed by the gain correction program and in no way affects the science data. CAO 11/12/2007
