Abstract
BudaLund hydro-model fits are compared to BRAHMS, PHENIX, PHOBOS and STAR data on identified particle spectra, two-particle BoseEinstein or HBT correlations, charged particle pseudorapidity distributions and pseudorapidity as well as pT dependent elliptic flow in and 200 GeV Au+Au collisions at RHIC. Preliminary results indicate that 7/8 of the particle emitting volume is rather cold, with surface temperature of 105 MeV, but the temperature has a distribution and the most central 1/8 of the volume is superheated to temperatures above the critical value, T(x) > Tc = 172 ± 3 MeV.
