Figure 7

Locations of corresponding points for all observers. The abscissa is the azimuth and the ordinate is the vertical eccentricity. The scale of the abscissa is expanded relative to the scale of the ordinate. The data are plotted in Hess coordinates, a system in which lines in the world map to lines in azimuth–elevation plots. At each eccentricity, the green and red dots indicate the locations of corresponding points in the left and right eyes, respectively. Error bars are 95% confidence intervals for azimuth measurements. Rotations due to cyclovergence (θh) and offsets due to fixation disparity were first subtracted from the data. We corrected for fixation disparity by finding the abscissa value at which the regression lines intersected, and then shifting the data horizontally such that the intersection had an ordinate value of zero.
