Hi Urs, Here's what I think we have now (unskimmed): 11.2 M (old) 9.3 M (new) of unskimmed B0 24.9 M (old) 30.1 M (new) of unskimmed B0 22.1 M (new) of unskimmed B0 those are 61M ev of new MC and ~ 35M ev of old MC (~96M ev in total) For Bch: 9.6 M (old) 11.5 M (new) of unskimmed B+ 24.9 M (old) 34.8 M (new) of unskimmed B+ 21.7 M (new) of unskimmed B+ those are ~67M ev of new MC and ~ 34M ev of old MC (~101M ev in total) All those files are contained in AWG12 (and I'm moving them right now in AWG18) and have a name in the format: unskgen*. I'm going to produce tcl files for the last produced MC generic collections with NO Ks bug and I'm going to put them in AWG18 with a format name like: unsk2gen* and unsk3gen Here's what I've found: 2976437 ev B+ new 2000 (~3M) 1030588 ev B+ new 2001 (~1M) 5735899 ev B+ new 2002 (~6M) unsk2* 10842682 ev B+ new 2002 (~10M) unsk3* 2587661 ev B0 new 2000 (~3M) 2289930 ev B0 new 2001 (~2M) 3888517 ev B0 new 2002 (~4M) unsk2* 13802518 ev B0 new 2002 (~13M) unsk3* So at the end I see: 83M B0 (new) and 87M B+ (new). We're still missing something :( . The script I'm usgin for MC generation is at slac ~asarti/script/TclUrsTool.pl (Concezio,can you please validate the run ranges I'm using?) Maybe those events have not been swept or are not in the skimData database.... I'm going to investigate a bit on that in the next few days... You can start using the tcl files in AWG18! I've also find out with Concezio that the tcl files for the unskimmed generic are containing also the runnumbers for the skimmed production that we did in august (there was a bug in the --newer flag used for generation of just 'newer' files..). In order to avoid duplicates we need to use JUST the unskimmed ones. We need to remove the /gen* files from our chains and use ONLY the /unsk* ones... (as already pointed out in a previous email). Let me know any doubt/question. Ciao, Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
