Specifically, we extract the renormalized values of <phi^2>/u and r/u^2 at the phase transition, where the continuum action of the theory is \\int d^3x [ (1/2) |\\grad\\phi|^2 + \\half r \\phi^2 + {u\\over4!} \\phi^4 ]. These values have applications to calculating the phase transition temperature of dilute or weakly-interacting Bose gases (both relativistic and non-relativistic).
