Plotted are ratios: T1/Q, T3/Q, T2/T1, T4/T3.
I.e. cross section and "junk", for kinematics 27 thru run 1451.
Results are from end-run scalers, are stable at approx 5% level.
About 1% of T4 are anomolous (should be T3). It occurs
to me that since the H-arm rate is 100 kHz the electronics
deadtime is of order 1%, this might explain it.
Since T4/T3 is 0.06, the effect is unimportant (<0.1%).
Note, T2/T1 = 8 but T2 are mostly zero-VDC-hit events (junk).
To make plot see /home/adaq/plt/README.
