Re: [Brahms-dev-l] Re: [Fwd: efficiencies]

Hi Bjorn and Zhongbao,
If I have a new local tracks files today, there will be a good chance 
that I manage
calculate the efficiencies before I do disappear for the Christmas holiday.

My plane is to provide T1,T2,T3,T4 and T5 efficiencies for pp runs and
T4, T5 for dAu.

I modified the efficiency code so we can support T5, even T3 tracks are
not present.
We will have T1 and T2 only for 8375 , and I would suggest to assume that
T1 and T2 have the same efficiencies as for p+p (we know that these 
detectors
are quite stable).  

Because, for d+Au we may have only Fs tracks with flag T2Used=kTRUE,
I would  suggest to utilize only Fs tracks with flag T2Used=kTRUE, both 
for p+p and d+Au.
I think that I will reduce the systematic error on R_dA, specially if 
you use the same acceptance maps.
Note, that if you decide to do this Bjorn has to modified Fs tracking setup:
by default we clean up T2-T4 tracks that have the same T4 track as any 
of T3-T4 , for
the mentioned purpose we have to revers the situation.
To let all the T2-T4 tracks survive the clean up just do:
  bfs->SetCleanUp(BrBfsTrackingModule::kCUT2, kFALSE);
  bfs->SetCleanUp(BrBfsTrackingModule::kCUT3, kTRUE);

Cheers
Pawel.
