Channel maps of the ¹²CO J = 1−0 and J = 2−1 line emission towards WX Psc. The maps are corrected for primary beam attenuation. The LSR velocities (units of km s^-1) are shown in the top-left corner of each panel. (Top) CO J = 1−0: contours start at 4σ and are in steps of 5σ with σ = 22 mJy beam^-1. Negative contours are plotted with the same spacing in dashed lines. The last panel shows the continuum emission with a contour spacing of 2σ and σ = 1.6 mJy beam^-1. The synthesized beam is at PA = 30°, and is drawn in the bottom-right corner of the two last panels. (Bottom) CO J = 2−1: contours start at 6σ and are in steps of 6σ with σ = 43 mJy beam^-1. Equivalent negative contours are plotted in dashed lines. The last panel shows the continuum emission with a contour spacing of 2σ and σ = 6.1 mJy beam^-1. The synthesized beam is at PA = 22°, and is drawn in the bottom-right corner of the two last panels. The map center coordinates are RA 01:06:25.990, Dec +12:35:53.40 (J2000).
