Abstract
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
