Our simulations suggest that higher harmonics provide a minimal amount of additional information, principally about source geometry. Higher harmonics do provide disproportionately more information than expected from the signal power. Our results compare favorably to the \"effective Fisher matrix\" approach. Extrapolating using analytic scalings, we expect higher harmonics will provide little new","authors_text":"(2) Northwestern University, (3) Department of Physics, (4) Department of Physics, B.
