1 - Pseudorapidity regions used in centrality
determination

Figure
2 - Midrapidity pseudorapidity density per participant pair as a
function of centrality at both energies.

Figure
3 - Same as figure 2 but normalized by data for p+p
-
Figure
4 - Ratio of the results for the two energies as a function of
centrality, also compared to models.
Data files are
available for 19.6 GeV, 200
GeV, and the ratio.
