CO(3–2) map averaged from 49 to 54 km s^-1. The crosses mark the positions of Mira A (west) and B (east). Contours are drawn at 3, 5, 10, 20, 40, and 80 times the rms noise level of the respective channel ranging from 30 to 160 mJy. The beam is shown in the lower left corner. A spiral is overplotted to clearly mark the spiral windings, and the accretion wake behind the companion is indicated.
