Ignoring the upper field improves motion estimates from optic flow measured in the native habitat of the zebrafish

We demonstrate the value of spatial biases by showing an advantage to excluding elevations from self-motion estimation across our dataset of natural optic flows. For velocity distribution and dataset size, see Table S2.

(A–C) We consider forward translation (A), heading (B), and rotation (C) errors for single RFs pairs, comparing with a baseline of using all elevations (dotted vertical line). When using a single elevation (first column), the best regions predicted by our simulations are equal to or outperform the baseline. When all but one elevations are used (second column), removing lower field samples damages performance while removing upper field samples improves it.
