Gain Notes for Revolution 782 JEM-X1: About half a day into this orbit the anode strip on the detector microstrip plate directly under calibration source 4 burnt out, with the result that all subsequent data from calibration source 4 is rubbish and can no longer be used for gain correction. This means that a new set of IMOD tables (epoch 19) must be used to correct this data properly, it is also recommended that OSA8.0 or later be used with this data due to significant temperature variations of the detector during this revolution. The new IMOD tables will be available along with OSA8 and then it will be possible to get a correct energy correction for this data. JEM-X2: No scientific data or gain history data for this unit.
