Corollary 6.21.

Let Σ\Sigma be a complete fan on NℝN_{\mathbb{R}} and L¯i=(Li,∥⋅∥i){\overline{L}}_{i}=(L_{i},\|\cdot\|_{i}), i=0,…,ni=0,\dots,n, be toric line bundles on XΣX_{\Sigma} generated by global sections and equipped with approachable toric metrics. Choose toric sections sis_{i} of LiL_{i} and let Ψi\Psi_{i} be the corresponding support functions. Then the toric height of XΣX_{\Sigma} with respect to L¯0,…,L¯n{\overline{L}}_{0},\dots,{\overline{L}}_{n} is given by

hL¯0,…,L¯ntor(XΣ)=MIM(ϑ∥⋅∥0,…,ϑ∥⋅∥n)=λKMIM(ψ∥⋅∥0∨,…,ψ∥⋅∥n∨).\operatorname{h}^{\operatorname{tor}}_{{\overline{L}}_{0},\dots,{\overline{L}}_{n}}(X_{\Sigma})=\operatorname{MI}_{M}(\vartheta_{\|\cdot\|_{0}},\dots,\vartheta_{\|\cdot\|_{n}})=\lambda_{K}\operatorname{MI}_{M}(\psi_{\|\cdot\|_{0}}^{\vee},\dots,\psi_{\|\cdot\|_{n}}^{\vee}).
