ALMA maps per velocity channel of ¹²CO J = 3−2 emission in R Aqr; see the LSR velocities in the upper left corners. The center is the centroid of the continuum, whose image has been subtracted. The contours are logarithmic with a jump of a factor 2 and a first level of ±5 mJy (equal to 6.2 times the rms and equivalent to 34.8 K); dashed contours represent negative values. The HPBW is shown in the inset, last panel.
