Gain Notes for Revolution 575 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 good, within about 2% of the ideal and within 1% of the ideal for most of the revolution after the usual warm-up period at the beginning of the revolution. However, as for all revolutions, the first few science windows should be avoided in any analysis requiring very good gain determination. JEM-X2: No scientific data or gain history data for this unit.
