• Figure 1 - Contains 3 panels

  • a) Paddle signal versus Npart from HIJING

  • b) ZDC signal versus paddle signal from data

  • c) Distribution of paddle signal showing location of cross section percentile cuts

• Figure 2 - Difference between Npart from HIJING and an optical approximation

• Figure 3 - Midrapidity dN/deta per participant pair versus centrality at 130 GeV. Several models and pp data also shown.

• Important Note: 130 GeV data were later reanalyzed which resulted in some small variation in the final numbers.  The shifts are smaller than the statistical and systematic uncertainties quoted in this reference.  Links to the updated values can be found here.  The same caution applies to the data values shown in Figure 3.
