The mass distribution for excess dielectrons in S + Au collisions at 200 A GeV measured by the CERES collaboration at CERN Super Proton Synchrotron is analyzed. The data are seen to be in satisfactory agreement with a scenario where a thermalized quark-gtuon plasma is formed initially, which expands
