The heterogeneity factor δ_α as defined in (5) is used to model the heterogeneous remodeling rate across the scleral shell. The heterogeneity factor is δ_α = 1 at the posterior sclera for |α| < π/4 and it gradually decreases to δ_α = 0 towards the anterior sclera for $\frac{\pi }{4}<|\alpha |<\frac{\pi }{2}$.
