data taken throughout entire shift.

everything was well behaved. cell temperature and ligit were constant. throughout the night, five fills were bad (i.e. really high wc scaler rates and low lifetimes). that seems quite high compared to what i observed last year.

fills are only to 100mA which slows the data rate. the red arrow maxed out around 200C/hr.

there is about 1kC of crunched data. that's not enough for a tensor polarization measurement. it's just barely enough for a beam-vector dilution measurement. show_deep_asym_all says that the beam-vector dilution is around 0.35 which gives Pz = 0.50 if h = 0.7. but i don't trust this reading on so little data.

good pol D2 runs:
