Fig. A.2.
Stereogram of the cube shown in Fig. A.1. Contours are drawn every 3, 6, 12, and 24 times the rms noise value in the spectral region of the bandpass without detectable line emission (σrms = 3.6 × 10−3 Jy beam−1). The channel at stellar velocity is shown in black dotted contours, and the mean red (blue)-shifted emission in red (blue). The green dashed line represents the symmetry axis of the map. The ALMA beam is shown in the bottom right (0.807″ × 0.768″).
