Channel maps of the ¹²CO J = 1−0 and J = 2−1 line emission towards TX Cam. 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 for 3, 7, 11, 23, and 35σ, and from there with a spacing of 21σ and with σ = 9.6 mJy beam^-1. In the channels labeled “c” in the bottom-left corner, contours at 15 and 19σ are also plotted. Negative contours are dashed and start at −3σ. The panel in the bottom-right corner shows the continuum emission with contours starting at 3σ, in steps of 6σ, with σ = 0.54 mJy beam^-1. The synthesized beam is at PA = 177°, and is drawn in the bottom-right corner of the two last panels. (Bottom) CO J = 2−1: contours are plotted from 7σ with a spacing of 12σ and with σ = 17 mJy beam^-1. In the panels labeled with “c” in the bottom-left corner an additional contour is plotted at 3σ. Equivalent negative contours are plotted with dashed lines. The last panel shows the continuum emission with contours from 3σ, a spacing of 6σ, with σ = 1.0 mJy beam^-1. The synthesized beam is at PA = 46°, and is drawn in the bottom-right corner of the two last panels. 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 05:00:51.157, Dec +56:10:54.00 (J2000).
