Rotation signatures retrieved at 225 au resolution by spectro-astrometry towards the low-velocity HH212 outflow. Blue (resp. red) contours show SO(9₈−8₇) blueshifted (resp. redshifted) emission over intermediate velocities (1.5 km s⁻¹ < ∣ V_LSR − V_sys∣ < 2.8 km s⁻¹) mapped with ALMA Cycle 0 (from Podio et al. 2015). The blue (resp. red) dots mark the centroid positions of transverse intensity cuts at each altitude across the blue (resp. red) contour maps. The black asterisk indicates the continuum peak. The jet was rotated to point upwards for clarity. Horizontal black dashed lines depict the position of PV cuts at z ± 70 au shown in Fig. 11. The clean beam FWHM of 0.65″ × 0.47″ is shown as afilled black ellipse. First contours are 0.1 mJy beam⁻¹ km s⁻¹ and steps are 0.15 mJy beam⁻¹ km s⁻¹.
