(a) plotted against T_pin. The entropy for inner sonic point solutions (black, dotted) and outer sonic points (black, solid) are presented. T_pin marked with green triangle corresponds to maximum entropy solution. Flow variables plotted are (b) M (green, solid), (c) v (cyan, solid) and v_ϕ (blue, dotted), (d) log n (magenta, solid), (e) T_p (red, dotted), T_e (orange, solid), (f) Γ_p (red, dotted), Γ_e (orange, solid), (g) E (brown, solid) as functions of log r. The flow parameters are E = 1.000045, λ = 2.5, Ṁ = 0.001 Ṁ_Edd and M_BH = 10 M_⊙. Panel b: the sonic point is marked with a black star.
