(Star type regions on XsX_{s}) On the region Uws⊂XsU^{s}_{w}\subset X_{s}, recall the coodinates zmiz^{m_{i}} and regard xmi=s−1​log⁡|zmi|x^{m_{i}}=s^{-1}\log|z^{m_{i}}| as local coordinates also on Uw∞∩∂Δλ∨U^{\infty}_{w}\cap\partial\Delta_{\lambda}^{\vee}. Let Uws,∗⊂Uw,δsU^{s,*}_{w}\subset U^{s}_{w,\delta} be the subset where the xmix^{m_{i}} coordinates correspond to points in Star​(w)⊂∂Δλ∨\text{Star}(w)\subset\partial\Delta_{\lambda}^{\vee}. The tropical analogue of Uws,∗U^{s,*}_{w} is (Star​(w)+ℝ≥0​w)∩Aλ∞(\text{Star}(w)+\mathbb{R}_{\geq 0}w)\cap A_{\lambda}^{\infty}.
