Comment on "Pairing and Phase Separation in a Polarized Fermi Gas" by G.   B. Partridge, W. Li, R. I. Kamar, Y. Liao, R. G. Hulet, Science 311, 503   (2006)
  We argue that it is not possible to infer from the results of Partridge et al. (Reports, 27 January 2006, p. 503) which of their data was taken in the superfluid or normal regime, and which of their clouds are phase-separated and which are not. Some of the conclusions in this paper are inconsistent with recent experiments.
