    keyword=NMR calibration and polarization measurement

    During a down this morning, I performed an NMR calibration. The beam had
    been off for 90 minutes and the last measurement had been about an hour
    beforehand.

    As a result of this calibration, I depolarized the target (due to the
    effeect of our measurement.) The final NMR yielded the following results:

    Lower
    X
    UP = 118.0 mV
    DOWN = 116.6 mV

    Y
    UP = 3.618 mV
    DOWN = 3.225 mV

    Upper
    X
    UP = 1.445 mV
    DOWN = 1.439 mV

    Y
    UP = 0.7087 mV
    DOWN = 0.7351 mV

    As a result, our polarization is: 50.57%
