    keyword=EPR is again creating masing

    While Vince was adjusting the photodiode fiber alignment, I performed EPR.

    The fisrt one gives a big loss of polarization about 8%.

    When the alignment was optimized I performed an EPR-NMR calibration.

    Now we shouldn't perform EPR unless we have a long down time. I looks like
    the masing is worse with Exodus that it was with Duke.

    The estimation of the EPR-NMR calibration constant is 2.47% per mV.
