Hi, Guannan

I understood the T0 change to have been implemented between the SL21b calibration production and the SL21c QA production, so I don't think there's something new to expect on that front. Someone can correct me if I misunderstand this.

Thanks for the observations on remaining dE/dx dependences on eta and momentum (however, I didn't see pT plotted, so there may be some convolution with eta).

Thanks,

-Gene

Hi Yuri, All.

The slides was updated accordingly with the new sample SL21cb. The mean value of nSigma was better, while the strong eta dependence and low pT offset for Kaon and Proton were still there. Not sure how the effect will be after new t0-start time implemented.

Hi Guannan, I will process SL21c with new calibration.

I have submitted them In /gpfs01/star/subsys-tpc/fisyak/reco/2019/19GeV/SL21cB.

It will take some time to get them done. I will appreciate if you can check them.

Hi Yuri,

 

Thanks for the information. The data set i checked is located below, sorry that there could be some miscommunication before since i thought these are two new samples with dEdx correction.  

/gpfs01/star/subsys-tpc/fisyak/reco/2019/19GeV/TFG21j/

/gpfs01/star/subsys-tpc/fisyak/reco/2019/19GeV/SL21c/

 

Anyway, Let me know when you have new samples available and I can take a look at them.

 

Best Regards,

Guannan

Hi Guannan, the SL21c sample has been produced before applying new correction to dE/dx.

The reason for this sample is to see difference between SL21b and SL21c.

It should be no changes with respect to P21ic in sense of dE/dx.

Dear Yuri, and All,

 

I take a  look at the new data sample produced by Yuri, the plots were posted below, Looks like the issue was still here? and I didn't see significant improvement. Can you double-check whether the new DB table was correctly implemented?

Dear Kaifeng, Ben, Guannan and QA team,

 

Yuri applied a time-dependent dEdx shift correction and ran a small test sample. Would appreciate that you can run a quick QA test using your existing codes to check the nSigma and nSigmaTOF(mass^2) mean positions again. 

 

Thanks and Regards
