Dear Ian, it does seem appropriate to use the grand-cononical ensemble in limited rapidity ranges for AuAu at least for dy=1. For smaller systems this breaks down obviously since their aren't enough particles. Currently we don't have a good micro-canonical approach for pp. Michael Here is my draft abstract for QM04.
