Fig. 1

Illustrative examples of spatial location estimates from the azimuthal telemetry model (ATM) and Lenth (1981) maximum likelihood estimator fit using the ‘sigloc’ package. The union of the gray circles are the region of uniform prior probability density for the spatial location (μi). Azimuthal uncertainty is defined as κ = 25. The inset shows the posterior distribution from the ATM at isopleths of 10, 25, 50, 75, and 95%. Plots that do not contain a sigloc estimate or uncertainty ellipse are because of estimation failure. a One Azimuth. b Two Non-Intersecting Azimuths. c Two Obtuse Azimuths. d Three Azimuths with Tight Intersections. e Three Acute Azimuths. f Three Azimuths with Poor Intersections
