A model is described for positioning cones in the retina. Each cone has a circular disk of influence, and the disks are tightly packed outward from the center. This model has three parameters that can vary with eccentricity: the mean radius of the cone disk, the standard deviation of the cone disk radius, and the standard deviation of postpacking jitter. Estimates for these parameters out to 1.6 deg are found by using measurements reported by Hirsch and Hylton [Vision Res. 24, 347 (1985)] and Hirsch and Miller [J. Opt. Soc. Am. A 4, 1481 (1987)] of the positions of the cone inner segments of an adult macaque. The estimation is based on fitting measures of variation in local intercone distances, and the fit to these measures is good.
描述了一种用于在视网膜中定位视锥细胞的模型。每个视锥细胞都有一个影响圆盘，这些圆盘从中心向外紧密排列。该模型有三个随偏心率变化的参数：视锥细胞圆盘的平均半径、视锥细胞圆盘半径的标准差以及填充后抖动的标准差。利用赫希和希尔顿[《视觉研究》24, 347 (1985)]以及赫希和米勒[《美国光学学会志A》4, 1481 (1987)]报道的成年猕猴视锥细胞内节位置的测量数据，得到了这些参数在1.6度范围内的估计值。该估计基于对局部视锥细胞间距离变化的拟合测量，并且与这些测量结果拟合良好。
