Spatial distribution of localization entropy.

<p>The entropy (in bits) about the origin of an echo as a function of reflector position, signal to noise ratio (15 to 45 ) and frequency. Left: results for the model in which the actual facial morphology of <i>R. rouxi</i> was included. Right: results for a model in which the emission pattern of <i>R. rouxi</i> was replaced by that of two isotropic sources. The plots cover the frontal hemisphere of the bat (−90 to +90 degrees in azimuth and elevation).
