There are some difference for kaon and pion for the tof matching efficiency. see attachment, tofMatch_TpcAna_0_10.gif

After require HFT, the difference was still there. see tofMatch_HftAna_0_10.gif

After remove YLocal cut, the tof match efficiency is higher, but the difference are still there.

checked with another data sample1 and full data sample, the results also show some difference.

Note here, the pion/kaon sample was selected using tpc only, say nSigma<0.3. If the cut was loose, we expect the difference will be reduce.
If pion/kaon samples was selected from ks/phi, the results could be change.
