[Nat.~Phys., \\textbf{11}, 1009 (2015)]. We observe a nonexponential collapse of the amplitude of the condensate oscillation followed by a partial revival. This behavior is identified as being due to beating between two eigenmodes of the system, corresponding to in-phase and out-of-phase oscillations of the condensed and noncondensed fractions of the gas. We perform finite temperature simulations of the system dynamics using the Zaremba-Nikuni","authors_text":"C. J. E. Straatsma, D. S. Lobser, D. Z. Anderson, E. A. Cornell, H. J. Lewandowski, M. J.
