  1. Artifacts of teleseismic body-wave inversion Don L. Anderson

  2. A cylinder (a) and a pillbox (b) both give a tent or cone plus rabbit ears when teleseismic body waves are inverted Slowness perturbations Keller et al.

  3. Examples of Rabbit Ear artifacts resulting from use of teleseismic body waves Foulger et al. Use of surface waves and regional events can suppress the artifacts West et al.

  4. Rabbit Ear artifacts result from use of teleseismic body waves Foulger et al. West et al. Wolfe et al. SCIENCE 2009

  5. Rabbit ears artifact Hawaii Yellowstone Rabbit ear artifacts? Wolfe et al. 2009

  6. The shallow anomaly is saturated but is about 3 %; the deep one about 0.5 % Result; 1 % with faint rabbit ears Test object; 2 % with Gaussian taper over 100-km Question: what would be the result if the test object were 3 %,with sharp edges?
