We prove sharp asymptotics for Christoffel functions @l"n(w^2^n,.) with respect to varying weights w^2^n. The result has an interpretation in the theory of statistical-mechanical models of quantum systems, and it is sufficiently strong to yield asymptotics for Christoffel functions for weights defined on several intervals.
