Transversity Analysis Meeting Jin Huang 2
Xin showed there are numerical scalar inconsistencies a_check/ a_check/ Examples: (Diff Between L&BB BCM scalar vs time) Transversity Analysis Meeting Jin Huang 3
Extract Slope of each plot Plot versus run number Four Main Categories: ◦ Helicity + VS Helicity Bigbite Scalars (Asymmetry) for helicity charge asymmetry study Helicity + VS Helicity Bigbite Scalars (Asymmetry) ◦ BCM x1 and x10 VS BCM Bigbite Scalars (Ratio) to check BCM problems on/after the amplifier BCM x1 and x10 VS BCM Bigbite Scalars (Ratio) ◦ BCM Upstream VS Bigbite Scalars (Asymmetry) to check BCM problems before the amplifier BCM Upstream VS Bigbite Scalars (Asymmetry) ◦ Bigbite Scalar VS HRS Scalars (Asymmetry) to check consistency between HRS and BigBite copy of each scalar channel Bigbite Scalar VS HRS Scalars (Asymmetry) Transversity Analysis Meeting Jin Huang 4
Following Link ScalarConsistCheck/ ScalarConsistCheck/ To Do: ◦ Check through all inconsistencies ◦ Build Problematic Run List Transversity Analysis Meeting Jin Huang 5

There is no much space to push ◦ No obvious slopes ◦ Also there is no ADC dependence (time walk has already done) Good News: For both BB & LHRS, there are obvious tails more than Gaussian TODO: ◦ Coding the coincidence module for replay ◦ Multi-hits; Multi-tracks: Golden track selection Transversity Analysis Meeting Jin Huang 9
