Channel maps of the ¹²CO J = 1−0 and J = 2−1 line emission toward IRAS 23321+6545 at the LSR velocities (units of km s^-1) specified 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, with a spacing of 3σ to 15σ, where σ = 6.5 mJy beam^-1. From 15σ contours are plotted every 6σ. Equivalent negative contours are plotted in dashed lines. The last panel presents the continuum emission with a first contour and contour spacing of 3σ, where σ = 0.4 mJy beam^-1. The synthesized beam, plotted in the bottom-right corner of last panels, is in size, with PA = 91°. (Bottom) CO J = 2−1: contours are plotted from 3σ, with a spacing of 4σ to 31σ, where σ = 10 mJy beam^-1. From 31σ contours are plotted every 10σ. In the panels marked with “c” in the bottom-left corner the contours are the same but that at 3σ is not plotted. Equivalent negative contours are plotted in dashed lines. The last panel presents the continuum emission with a first contour and contour spacing of 3σ, where σ = 0.7 mJy beam^-1. The synthesized beam, plotted in the bottom-right corner of last panels, is in size, with PA = 127°. The central coordinates are RA 23:34:22.52, Dec 66:01:51.5 (J2000).
