Gain Calibration Notes for Rev. 368
	
Relatively little noise and no large glitches. The rise
at the beginning of the revolution is due to ion motion in the microstrip plate
that occurs after the switch on of the high voltage to the plate. Also some
indication of a small decay immediately after switch on, but nothing that
affects the gain smoothing. Also a robust glitch on Source 4 (Cd) - it should
be noted that this is the noisiest of the four source positions, as it is on
JEM-X2.

The Xe line analysis shows that the gain correction has worked quite well for
the revolution, with the Xe line position within +-2% of the ideal value except
for the first couple of science windows, which should be treated with due
caution.
