Stereogram view of the continuum subtracted ¹²CO J = 3−2 (left panel) and ¹³CO J = 3−2 (right panel) data. The blue (red) contours correspond to the velocity-averaged emission profile of 98% of the blue-shifted (red-shifted) wing of line. The black dashed contours correspond to the velocity-averaged emission of the central 2% of the emission line. The contours are drawn at every 2.5 times the continuum rms noise value (¹²CO: 2.5 mJybeam^-1, ¹³CO: 2.6 mJy beam^-1). This figure appeared in Kervella et al. (2016), and is repeated here as a guide.
