Gain Notes for Revolution 425
	
JEM-X1: This is a perfectly normal and well-behaved revolution. 
The gain fitting has performed without
problems, and all the data from this revolution should be useable. The big
glitch on source 1 (black/red) and the two strong glitches on source 3 (blue/green)
appear to be simultaneous, but a look at the data in more detail reveals them
to be quite independent of each other, though all good cases of classic glitches.
Also, the source that lies between these two shows no glitch activity at this
point in the revolution, so we can be certain that we have not seen the first
spatially extended glitch, which would be quite a problem if it occurred.
Users should be aware that as we reach the solar minimum particle activity
increases, and this also increases the glitch rate on the plate. While this
is easy to smooth out in the gain calibration data, it will  however, lead to a
decrease in energy resolution as these gain transients pop up randomly all over
the microstrip plate.

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