(a) PV diagram of 12CO (1–0) across the PV cut indicated by the red dashed line in Fig. 8a. The overlaid contours represent the PV diagram of 13CO (1–0). The contours start at 0.9 K (3σ) and increaseby 1.8 K. The systemic velocities of L1188a and L1188b are indicated by two blue vertical dashed lines. (b) Similar to a, but for 12CO (2–1). The weak low-velocity wing emission is indicated by the red dashed box. (c) Similar to a, but for 12CO (3–2). The three arrows represent the high-velocity wing emission discussed in Sect. 3.2. In all panels, the offsets are given with respect to the southeastern end of the PV cut. The red dashed line is used to highlight the high-velocity wings, which can be recognized on the left hand side of the red dashed line.
