The line profiles of C18O (2–1), HNC (1–0), and N2H+ (1–0), extracted from synthesized beam-averaged regions centered on core10, positions A, B, and C (as shown in Figure 1). The vertical red dashed line indicates the systemic velocity, and the shaded region shows the integrated velocity range for the ring component.
