Gain Notes for Revolution 517 JEM-X1: A quite normal revolution with okay gain fitting. All the data from this revolution should be useable. However, the gain smoothing shows some signs of not following the temperature changes in the instrument particularly well (a problem that will be tackled with the next software upgrade) and therefore the gain correction may be off by a couple of percent in some places during the revolution. The Xe line analysis shows that apart from the usual danger area just after switch on, the Xe line lies more or less where it should, indicating that the gain correction has in fact has worked well JEM-X2: No scientific data or gain history for this unit.
