Table A1.

This table contains the mean and standard deviation SED values corresponding to the individual heat maps in Figure 1. To compute standard deviation, we drew 10,000 bootstrap samples of left eye (LE) and right eye (RE) durations from each zone’s LE and RE data pool for each individual observer. The number of data points in the LE and RE samples were always matched to the observed number of LE and RE data points in each zone [16]. In the table below, eccentricity (ecc) is in degrees of visual angle. The direction (dir) refers to the position of the rival patches relative to fixation, with 0 directly to the left of fixation, and increasing numbers moving clockwise around a circle. In other words, 0 corresponds to West on a compass, 90 to North, etc. Positive numbers correspond to RE dominance; negative numbers to LE.
