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 beam⁻¹, equal to 6.2times the rms and equivalent to 34.8 K (in Rayleigh–Jeans-equivalent brightness temperature units). The dashed contours represent negative values. The HPBW is shown in the inset in the last panel.
