Typical configuration of points in physical space that served as input to the model. It consisted of 40 points arranged in a polar grid. The center of the grid corresponded to visual fixation. The points were arranged over five eccentricities, at [1, 2, 4, 6, 8] degrees of visual angle. At each eccentricity, eight points were placed in a circle at 45° increments.
