[Brahms-dev-l] Re: [Brahms-l] 62.4 GeV Nbin/Npart

Hi Hiro,

Sorry, I should have been more precise in my wording. The question was
really if we (as a collaboration) have standard Npart and Nbin numbers for
the 62.4 data? It's great that you tell us how to estimate the numbers,
but I think we should have (only) one set of numbers so that we are
consistent, at least within the collaboration. Also, the method you
suggest will not give the errors on Npart and Nbin or tell how large a
fraction of all inel collisions was recorded... but thanks anyway for the
update.

Cheers,

Claus
