ALMA ¹²CO J = 3−2 observations of the Red Rectangle. The maps are centered at J2000 coordinates 06:19:58.205, − 10:38:15.00. The LSR velocity is indicated in the upper-left corners. The contour spacing is logarithmic: − 0.03, 0.02, 0.06, 0.18, 0.54, and 1.62 Jy/beam (equivalent to 0.67, 2.0, 6.1, 18.2, and 54.5 K). The HST optical image is also displayed, and the last panel shows the 0.85mm continuum image zoomed by a factor 2 and with contours ±0.0015, 0.0045, 0.0135, 0.0405, 0.1215, and 0.3645 Jy/beam. The inserts in the two last panels show the beam width.
