Here are the new results. Keep in mind that this is a calibration against the clock at 103.7 KHz.
U1 coeff=41.35+/-0.15 const=-0.220+/-0.038 U3 coeff=13.41+/-0.07 const=-0.039+/-0.016 U10 coeff= 8.84+/-0.04 const=-0.005+/-0.009 D1 coeff=37.53+/-0.13 const=-0.078+/-0.037 D3 coeff=12.09+/-0.06 const=-0.008+/-0.016 D10 coeff= 3.84+/-0.02 const= 0.003+/-0.009Based on these results I think we are find working with a beam current above 1 uA. Though above 2 uA is better. The script /adaqfs/home/adaq/dvcs/onlana/charge.C computes the charge accumulated during a run using the 6 bcm signals.
