Dear JH, this seems like a good idea. why aren't the different a regions symetric about the peak? It seemed to me that you were only using 7 regions but that your index ran over 8.

Here is what I believe one of the ways to accommodate the uncertainties in applying z dependent acceptance weight. This method doesn't require generating new maps and has been "successfully" adapted in the Ramiro's analysis. http://pii3.brahms.bnl.gov/~jhlee/brahms/analysis/acceptance/new_acceptance_ weighting_for_forward_in_dAu.pdf Cheers, JH _______________________________________________ Brahms-dev-l mailing list Brahms-dev-l@lists.bnl.gov http://lists.bnl.gov/mailman/listinfo/brahms-dev-lReceived on Sat Jan 24 21:57:31 2004
