Notes. The table lists: sequential number in Figs. 17 and 18, the composition of the heat blanketing envelope, assumed impurity parameter Qimp in the accreted crust, the model of the non-accreted crust bottom (pure ground state or equilibrium composition according to Sect. 3.2), mean long-term accretion rate ⟨Ṁ⟩−10 ≡ ⟨Ṁ⟩/(10−10 M⊙ yr−1), and shallow heat per accreted baryon Esh.
