has lagged. While it is quite clear that - under conditions of equipartition - such correlations
ought to converge on the Green's function, it is less clear how much we should trust the results
when the ambient waves do not satisfy the conditions.
I review a few of the proofs and laboratory demonstrations, paying particular attention to the
degree of equipartition present in each case and estimates for the quality of convergence.
In many circumstances one can show that a laboratory or seismic correlation, even when the
averaging is essentially converged, does not correspond to the Green's function. The
discrepancy is traceable to an insufficiently diffuse and equipartitioned noise field. I discuss one
way to finesse this failure of the conditions; a numerical example is offered.
