Gain Notes for Revolution 281
	
JEM-X1: A completely ordinary revolution. Gain smoothing is fine except for the
source 2 gain increase immediately after full switch-on. Data from these
initial settling periods should generally be avoided for spectral purposes. 
All other data (after about IJD 1857.15) from this revolution should be useable.
First two data points on each data set are the  pre-switch on with High 
Voltage 3 steps below its nominal value.
