Gain Notes for Revolution 301 A completely ordinary revolution,interrupted by very short break that has no effect on the gain. Gain smoothing is fine, except for very beginning of revolution where fit for source 1 is poor (program has chosen to make a long slow decay over half the revolution instead of a short increase in gain at the very beginning). This will compromise gain correction upto IJD=1917.1, but all of the data thereafter should be useable. First two points in data set are pre-switch on of High Voltage at three steps below its nominal setting. CAO 4/11/2005
