[Rgc_analysis] [Rgc] TPOL

[Christopher Keith]

The NMR averaged 36% during Run 17577, but its calibration constant (2.54) is not believed to be very accurate.  When we last ran 15 mm proton cells in Sept., we found a higher number (3.67).  If we use that, the NMR goes up to 52%.  Still lower than the inclusive results, but closer.  The online trigger asymmetry (B_DAQ:HEL:60m:29:pol) averaged 69 +/- 0.02%.
