Schematic plot of the calculation domain for a ballistic orbit (solid orange line) with M _BH = 10⁷ M _⊙, M _* = M _⊙, R _* = R _⊙, and β = 1.0. The black frame shows the calculation domain we adopt in A122Edd1, A122Edd01, A122Edd001, and A122Edd10. The blue frame shows the SMR region with level = 5. The red frame shows the SMR region with level = 6 near the shock. The black star shows the position of the black hole (−L ₁₂, π/2, π).
