Gain Notes for Revolution 515
	
JEM-X1: Large temperature changes in this revolution make the instrument gain
dip and rise sharply. Unfortunately the gain smoothing does not follow these
changes as well as it might, and we can expect some degradation in the gain
correction at some places in this revolution. The Xe line analysis of the
available survey data shows that the Xenon line lies almost exactly where it
should, though nothing can be said for certain about the rest of the revolution.
However, it would appear that the gain correction has worked well.

JEM-X2: No scientific data or gain history for this unit.
