Channel maps of the ¹²CO J = 1−0 and J = 2−1 line emission towards RX Boo. The LSR velocities (units of km s^-1) are shown in the top-left corner of each panel. No primary beam attenuation correction is applied. (Top) CO J = 1−0: contours are plotted from 3σ in steps of 3σ with σ = 16 mJy beam^-1. Equivalent negative contours are plotted with dashed lines. The last panel shows the continuum emission with contours starting at 3σ in steps of 3σ with σ = 0.6 mJy beam^-1, and the synthesized beam in the bottom-right corner of size at PA = 41°. (Bottom) CO J = 2−1: contours are plotted from 3σ in steps of 3σ with σ = 29 mJy beam^-1. Equivalent negative contours are plotted with dashed lines. The last panel shows the continuum emission with contours starting at 3σ in steps of 3σ with σ = 1.5 mJy beam^-1, and the synthesized beam in the bottom-right corner of size at PA = 24°. The primary beams are plotted at half power, in dotted lines, in the last panels of the channel maps. The map center coordinates are RA 14:24:11.626, Dec +25:42:13.18 (J2000).
