Buda-Lund hydro model fits are compared to BRAHMS, PHENIX, PHOBOS and STAR data on identified particle spectra, two-particle Bose-Einstein or HBT correlations, charged particle pseudorapidity distributions and pseudorapidity as well as p_t dependent elliptic flow in sqrt(s_NN) = 130 and 200 GeV Au+Au collisions at RHIC. Preliminary results indicate that 7/8-th 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-th of the volume is superheated to temperatures above the critical value, T(x) > T_c = 172 \pm 3 MeV.
