    keyword=NMR calibration mistake & polarization after 1 run

    at 13:41 I measured the NMR on he3 position again(beam is down).
    after JP mentioned my mistake(there is a large offset on pumping chamber signal which I didn't take into account) on NMR calibration, I re-calculte the coefficient(it's 2.3675 now) and finally get a result about 45%
