Same as Fig. A.1, but for variation in average outburst accretion rate. For the models shows in this figure, the outburst accretion rate (Ṁ_o), is multiplied by a factor of f_a. The solid lines are for model 1 (which has a time-averaged accretion rate ⟨Ṁ⟩ = 3.2 × 10⁻¹⁰ M_⊙ yr⁻¹), the dotted line for model 3 (⟨Ṁ⟩ = 6.4 × 10⁻¹² M_⊙ yr⁻¹), the dashed-dotted line for model 4 (⟨Ṁ⟩ = 3.2 × 10⁻¹¹ M_⊙ yr⁻¹), the dashed lines for model 5 (⟨Ṁ⟩ = 1.6 × 10⁻¹⁰ M_⊙ yr⁻¹), and the short dashed-dotted curves for model 6 (⟨Ṁ⟩ = 6.4 × 10⁻¹⁰ M_⊙ yr⁻¹).
