CO J = 1–0 maps of blueshifted (V_LSR = −1.04–11.12 km s⁻¹; blue contours) and redshifted (V_LSR = 11.93–24.08 km s⁻¹; red contours) emission taken by the NMA superposed on the CS J = 3–2 integrated intensity map taken by the 45 m telescope (green shaded). The contours of the CO J = 1–0 maps are drawn every 1.7 Jy km s⁻¹ beam⁻¹ (1 σ) from the 3.4 Jy km s⁻¹ beam⁻¹ (2 σ) level. The contours of the CS J = 3–2 map are drawn in the same manner as in Fig. 1b. The positions of two radio continuum sources (VLA 1 and VLA 2) and HH objects identified by Vrba et al. (1986) (HH 82 and HH 84) are indicated by crosses.
