Gain Notes for Revolution 443 JEM-X1: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. The Xe analysis confirms that the energy determination for this revolution is excelletn, within about 1% of the ideal. However, as for all revolutions, the first few science windows should be avoided in any analysis requiring very good gain determination. An unusually large glitch is visible on source 4 (purple/orange), about 30% drop in gain. There is another large glitch later in the revolution. Neither of these glitches in any way affect the gain smoothing and the gain correction of the science data. JEM-X2: No scientific data or gain history data for this unit. CAO 4/07/2008
