Gain Notes for Revolution 134 JEM-X2: A quite normal revolution with fine gain fitting. All the data from this revolution should be useable. First few points on each curve belong to the partial switch-on for which HV is set 3 steps below its nominal value. The break towards the end of the revolution is well-fitted but marks a period during which tests were carried out on the calibration source collection areas so that calibration events appeared in the science data. This period is now officially designated a BTI, since response is not measured at all during this period through the official routes. The BTI is: IJD= 1419.53 to 1419.74. CAO 10/11/2006
