    "abstract": "We have studied one-body and two-body correlation functions in a\nballistically expanding, non-interacting atomic cloud in the presence of\ngravity. We find that the correlation functions are equivalent to those at\nthermal equilibrium in the trap with an appropriate rescaling of the\ncoordinates. We derive simple expressions for the correlation lengths and give\nsome physical interpretations. Finally a simple model to take into account\nfinite detector resolution is discussed.",
