Gain Notes for Revolution 357
	
JEM-X1: Revolution with a late switch on after some heavy space weather. The
instrument had been switched off for 2 whole revolutions prior to being switched
on fairly late in this revolution, due to high solar activity. This means that
there is an extra long period of gain recovery after switch on leading to a
steady increase in the position of the Xe line determined for each Science
Window. The sharp dip midway through the data occurs during a period time when
there was heavy grey filtering as strong sources passed through the FOV, and is
probably not significant, but will be investigated further to see whether further
corrections are needed.
