Using the Floer degree formula (63), the asymptotic behaviour of $\Omega(v_{1},\ldots v_{n})$ at the corners can be extracted from the above proof: at the $CF^{0}(L,L^{\prime})$ corner point $p$

$$\Omega(v_{1},\ldots v_{n})=a_{p}z^{(\theta_{L^{\prime}}-\theta_{L})(p)/\pi}(1+O(z)),\quad a_{p}\neq 0,\quad\arg a_{p}=\theta_{L}(p)\mod\pi\mathbb{Z}.$$

At the degree one self intersections $p_{l}\in CF^{1}(L_{+},L_{-})$ on $L$ or $L^{\prime}$,

$$\Omega(v_{1},\ldots v_{n})=a_{l}z^{(\theta_{L_{-}}-\theta_{L_{+}})(p_{l})/\pi}(1+O(z)),\quad a_{l}\neq 0,\quad\arg a_{l}=\theta_{L_{+}}(p_{l})\mod\pi\mathbb{Z}.$$

At the degree $n$ output $q$,

$$\Omega(v_{1},\ldots v_{n})=a_{q}z^{(\theta_{L}-\theta_{L^{\prime}})(q)/\pi}(1+O(z)),\quad a_{q}\neq 0,\quad\arg a_{q}=\theta_{L^{\prime}}(q)\mod\pi\mathbb{Z}.$$
