Caption: Figure 5.

Fitted ballistic orbit (dashed lines) for the spoke-like features (markers) denoted as A1, A2, B1, and B2 in the lower panels of the velocity–position map. Blue represents the v = 1 J = 1 → 0 SiO maser, and red represents the v = 2 J = 1 → 0 SiO maser. Fitted parameters and their uncertainties are shown in the bottom right corner. Upper panels: Parameters of M, r₀, and i (see the text for definitions) are determined from the Nelder–Mead algorithm at the same time for each spoke-like feature. Lower panels: Parameters of r₀ and i are determined from a simple nonlinear least squares curve fitting method using the average stellar mass, 5.8 M_⊙, obtained from the upper panels.
