keyword=Left arm scalerWolfgang and Xiaochao mentioned that for some runs in the scaler file:
charge(hel + gated) + charge( hel - gated)> charge( ungated) , which conficts with what we used to believe. However, it happens only with left arm scalers since g2 started.
Fig1 shows the runs of g2
topleft: (sum of gated clock)-(ungated clock) for left arm , as it shows: (sum of gated clock)>(ungated clock), it looks strange.
topright :( sum of gated charge)-(ungated charge) for left arm.
bottomleft: (sum of gated clock)-(ungated clock) for right arm , it looks normal.
bottomright :( sum of gated charge)-(ungated charge) for right arm
Fig 2 shows the similar plots for all the A1 runs, all seems reasonable: (sum of gated counts)<(ungated counts);
