### Reco/tgen thrust 2PC difference investigation
+ [ ] reco/tgen ratio: https://hep1.phys.ntu.edu.tw/~willylin/RecoGenRatio/Summary.html
    + refined with Ntrkoffline bin: https://hep1.phys.ntu.edu.tw/~willylin/RecoGenRatio/NtrkofflineSummary.html
+ [ ] smearing effect (genThrust)
    + Result:
      + Onres: https://hep1.phys.ntu.edu.tw/~willylin/genThrust/OnresSummary.html
      + Conti: https://hep1.phys.ntu.edu.tw/~willylin/genThrust/ContiSummary.html
    + (if genThrust guess is correct) do pt cut before thrust axis calculation
        + Result:
+ [ ] pure generator without HadronB skim
    + Result: 
        + Onres (beam axis) https://hep1.phys.ntu.edu.tw/~willylin/genSample/BeamOnresSummary.html
        + Onres (thrust axis) https://hep1.phys.ntu.edu.tw/~willylin/genSample/ThrustOnresSummary.html
        + Conti (beam axis) https://hep1.phys.ntu.edu.tw/~willylin/genSample/BeamContiSummary.html
        + Conti (thrust axis) https://hep1.phys.ntu.edu.tw/~willylin/genSample/ThrustContiSummary.html
+ [ ] check on pseudorapidity
    + Eta binning study:
        + Onres: https://hep1.phys.ntu.edu.tw/~willylin/EtaCut_Thr/OnresSummary.html
        + Conti: https://hep1.phys.ntu.edu.tw/~willylin/EtaCut_Thr/ContiSummary.html
+ [ ] closure test on thrust axis variable
    + closure test: https://hep1.phys.ntu.edu.tw/~willylin/ThrustEffTable/ClosureTest.html
        + in $\theta_{T}$ bins
            + Original table: https://hep1.phys.ntu.edu.tw/~willylin/ThrustEffTable/TThetaCut/ClosureTest.html
            + New table(correct by $\phi_{\rm thrust}$): https://hep1.phys.ntu.edu.tw/~willylin/ThrustEffTable/TThetaCut/ClosureTest_thrustTable.html
    + test on new efficiency table(correct by $\phi_{\rm thrust}$)
        + Onres: https://hep1.phys.ntu.edu.tw/~willylin/ThrustEffTable/OnresSummary.html
        + Conti: https://hep1.phys.ntu.edu.tw/~willylin/ThrustEffTable/ContiSummary.html
+ [ ] $\theta_{T}$ cut study
    + Onres: https://hep1.phys.ntu.edu.tw/~willylin/TThetaCut/OnresSummary.html
    + Conti: https://hep1.phys.ntu.edu.tw/~willylin/TThetaCut/ContiSummary.html
+ [ ] [bbg](https://hep1.phys.ntu.edu.tw/~janicechen/BBGStudy_v2_thrustAxisWoBBG/ntrk6conti/index.html):
    + [ ] (bbg x bbg), (bbg x !bbg) 2PC // to see where bbg can be contributed to in 2PC.
    + [ ] reco level TPCNtuple w/o bbg -> reco Thrust axis could be different. (take away BBG contribution)
        > Assumptions:
        > ~~+ [ ] reco level using genThrust can correct the additional ridge (back to gen level).~~
        > 
        > Possible solution: make pt cut to veto very soft ptl (bbg enhance region) before calculating event thrust.
        > 
+ [ ] [Reco Peak Gen Dip Problem](https://hackmd.io/A6m00EeJSni6HFGHv5k98Q?both)
    + [ ] reco problem: duplicate-track-removing-algo pt threshold: 0.25 GeV, need refined
    + [ ] gen problem: need to take care of some decay of the intermediate state ptl.

### Referee question
+ [ ] ISR:
    + [ ] ISR w/ accetpance cut (current config)
    + [ ] ISR w/o acceptance cut
    + [ ] w/o ISR
