ALMA maps per velocity channel of ¹³CO J = 3−2 emission in R Aqr (only the more extended array configuration); see the LSR velocities in the upper left corners. The center is the centroid of the continuum, whose image has been subtracted. The logarithmic contours and scales are the same as in Fig. 1 (in this case, the first contour, 5 mJy beam⁻¹, is equivalentto 5.6 times the rms and 35.2 K). The HPBW is shown in the inset in the last panel.
