Definition 6.4.

Let ℒ#{\mathcal{L}}^{\#} be a residually metrized model of KXK_{X}, determined on a proper dlt model 𝒳{\mathcal{X}} of XX. To ℒ#{\mathcal{L}}^{\#} we associate a positive measure μℒ#\mu_{{\mathcal{L}}^{\#}} on Δ⁡(ℒ)⊂Δ⁡(𝒳)\Delta({\mathcal{L}})\subset\Delta({\mathcal{X}}) defined by

μℒ#=∑σ(∫YσResYσ⁡(ℒ#))​bσ−1​λσ,\mu_{{\mathcal{L}}^{\#}}=\sum_{\sigma}\left(\int_{Y_{\sigma}}\operatorname{Res}_{Y_{\sigma}}({\mathcal{L}}^{\#})\right)b_{\sigma}^{-1}\lambda_{\sigma},

where σ\sigma runs over the top-dimensional faces of Δ⁡(ℒ)\Delta({\mathcal{L}}).
