Charged Particle, Photon Multiplicity, and Transverse Energy Production in High-Energy Heavy-Ion Collisions
Figure 35
The midrapidity () minimum bias distribution of total transverse energy along with distributions for different centrality bins for GeV, as is measured by the STAR experiment at RHIC. The shaded area corresponds to the most central bin. The main axis scale corresponds to the measured in the detector acceptance and the bottom axis is corrected to represent the extrapolation to full azimuthal acceptance. The figure demonstrates the use of distribution for estimation of collision centrality. The figure is taken from [64].
