    Entry number 290171

    This entry is a followup to: 290108

    keyword=Compton Data

    The Compton asymmetry for run 19453 has large error bars because it is only a 10 minute run. Run 19452 has a gain shift presumably due to the fact that beam and laser had just come back on. The first figure is the accumulator 0 signal as a function of time for run 19452. Note the decrease in gain. The second is the same as the figure in entry 290108 but with an extra point.
