    keyword=harp scan for 1.7GeV setting

    I did the harp scan this night, since Trent changed the gain, I took the
    calibration run for this new gain, also I took for old gain setting. the
    current I took is 100nA,75nA,50nA.
    Since MCC failed to raise current to 2uA pulser, I took the harp scan in
    2uA pulser . the signal is noise , you can see the snapshot in:
