By that I mean removing junk runs, keeping only those with some significant number of events, and only keeping those with physics trigger settings (not special runs).  For that we need a run list.  I think we have close to a PB, but I remember hearing at the collaboration meeting that at least 20% is not useful for the porpoises of trigger bit skimming.
