    keyword=Target - EPR 37.3%

    3:15 ~ 3:40: Did one EPR after reference N2 run. Laser #6, oven 170, photodiode
    signal DC 170mV, looks normal. But at first couldn't find the D2 signal. Both X
    and Y channels of Lock-in were jumping crazily. Noticed the fluke reading is
    -6.91, expect resonance at 11.4 MHz.
    Then asked MCC to stop beam and mask the target. Two minutes after the target
    was masked, Lock-in signals look fine. System locked to 11.37 MHz, did one AFP
    measurement, tuned Mod souce from 0.7 Vpp (at the begining and flipping down)
    to 1.0 Vpp (during flipping up).

    Frequency shift 44.9 KHz, polarization 37.3 %.
