Three-color image constructed with integrated 12 m+7 m C¹⁸O(2–1) emission (−23.0 to 20.5 km s⁻¹ in blue, −20.5 to −19.5 km s⁻¹ in green, and −19.5 to 17.0 km s⁻¹ in red). The synthesized beam (1.″56 × 1.″40) is shown in the lower left corner. The 7 m continuum image is shown in white contours for comparison. The contour levels are 1.7 mJy beam⁻¹ × (3, 6, 10, 20, 50, 100).
