Hi EunJoo I have looked a little bit at my old stuff for finding the time row corrections and it even confuses me. Unfortunately it will not be finished before I leave for 2 weeks. If you need it faster write me and I will give you short description of how to proceed. A very short description : http://www.nbi.dk/~pchristi/BRAHMS/TPC/timerow.html I made the first step outlined on the page and have the trees /direct/brahms+u/pchristi/scripts/brahms_app/pc_app/tpc/newtimerow TPM2timerow.old.root TPM1timerow.old.root T2timerow.old.root T1timerow.old.root There are trees that you can look at, I could not get my automatic scripts to work.... do fx : T->Draw("dy:y", "row==2&&chi2<50") y and dy are in timebins. Then you can see the row time correction. Fit the profile with a pol1 and use the corrections in your script (That is probably also the only way to figure out the sign).
