    "abstract": "For a non-self-interacting Bose gas with a fixed, large number of particles\nconfined to a trap, as the ground state occupation becomes macroscopic, the\ncondensate number fluctuations remain micrscopic. However, this is the only\nsignificant aspect in which the grand canonical description differs from\ncanonical or microcanonical in the thermodynamic limit. General arguments and\nestimates including some vanishingly small quantities are compared to explicit,\nfixed-number calculations for 10^2 to 10^6 particles.",
