Example 3.13 (A variation).

Again, we can perturb the above example by replacing the straight edges of Δ\Delta with smooth curves starting at the origin. This time these curves have to be contained inside {0}×ℝ2\{0\}\times\mathbb{R}^{2}, which is the integral surface (containing Δ\Delta) of the distribution spanned by the ρ\rho-holonomy invariant vectors in T​B0TB_{0}. The perturbed Δ\Delta, which we could denote Δτ\Delta_{\tau}, still separates ℝ2\mathbb{R}^{2} in three connected components C1,C2C_{1},C_{2} and C3C_{3}. Then the definition of the affine structure carries through just like in the previous example and we denote it by 𝒜τ\mathscr{A}_{\tau}.
