Hi Selemon, I'm glad that it works. If you have found that some important information is missing in the README file, fill free to update the file. Concerning T4 (B setting, runs: 14339-14348): the latest ltr production was done on 2005-09-24. We discovered the T4 efficeincy problem (on last year) looking at other settings and the DC tracking code was updated on 2006-10-27 to enhance the efficiencies in T4. I think that after that Flemming re-run ltrs for runs showing the problem but probably not for all of them. I suggest you to redo ltrs for one run (e.g. 14339) and see whether new T4 efficiency is reasonable (on the level of 95%), if so, redo the whole set. Concerning H2/H1 efficiencies, Although efficiency files contain maps for H1 and H2 one should not rely on them, because the track versus tof hit matching criteria used in the efficiency stuff are not identical as these applied in the reconstruction chain. Once I tried to fixed it but could not easily understand of how this matching is done in the brat. But it fact what we need for H1/H2 is the final pid efficiency (=efficiency that the hit was detected, matched to track and then successfully used to identify the track). We can retrieve this final pid efficiencies in the similar way as we do it for Rich (e.g. from the dst files). Maybe I will show the example of such analysis on the coming phone meeting. Cheers, Pawel.
