This paper presents a metric useful in analyzing the resolution of multidimensional parameter estimators which produce normal, unbiased estimates. The metric is based on the distance between ellipsoidal level curves of the individual estimates' densities. The resolution threshold is deemed to be the lowest SNR at which ellipsoids enclosing a given amount of probability mass have disjoint interiors. This paper develops an algorithm which computes the threshold by studying the problem of finding the distance between two ellipsoids.<
