The rapidity distribution of highest pt particles (pt > 1.5 GeV/c) for dAu2008 and dAu2003 appears to be

different in the range |y|<0.8, especially for y between 0 and +0.8.  The two distributions are below.  Does

anyone know why this might be so different?

In the preliminary centrality results for dAu2008, the refmult distributions on the page

     http://drupal.star.bnl.gov/STAR/blog-entry/dunlop/2008/oct/14/first-attempt-do-centrality-using-bbc-d-au-run-8

suggest that there are more peripheral events in dAu03 than dAu08.  There is a difference in my min-bias

correlation functions for the two data sets which seem to suggest the opposite may be true.  Is it possible the labels

on the graphs in the above link got switched?  The correlation functions showing this are further below.

The dN/dy distribution for dAu2003 (using trigger id's 2001 & 2003) looks like...

and for dAu 2008 (using trigger id 210020) the dN/dy distribution is ...

The "min-bias" correlation function for dAu2003 (trigger id's 2001 and 2003)  using a spherical harmonic decomposition is

and the same correlation function using dAu2008 (trigger id 210020) is

The A20 (top right) graph should be further below zero when there are more peripheral collisions.  These results would make more sense if there were more peripheral events in dAu08 than dAu03 which is opposite of what the refmult() distribitions on the previous post suggest.
