Hi Felix,


OK, That is clear to me that STT mode has been done with global reconstruction with MVD+GEM+STT, but TPC dosen't.
Then difference of global efficiency can be understood.
So you mean that I need to require some STT hits in the analysis sample to make real comparison.

Then, next question is how many hits would be reasonable in the STT sample 2,4,or 10? or even more?

I think for TPC the final sample surely have more than 100 MC points for summed up all 6 charged tracks.(of course I will check with data) Smile
thank you for you comments.

Best wishes,
Donghee
