Gain Notes for Revolution 361 JEM-X1: Much less noise and far fewer glitches than some previous revolutions due to the quieter space weather recently. Otherwise, nothing to report here. The Xenon line analysis shows that the Xe line is well within the 29-30keV range for most of the revolution. The only time period where the Xe line was outside the 29-30 keV range was at the very beginning of the revolution just after switch on. Users should be cautious when using these first science windows in a revolution for critical spectral analyses. Otherwise, the gain correction has worked very well. CAO 7/2/2007
