Same as Fig. 21 but showing the comparison between CO(2–1) (contours) and [SiVI] (color scale spanning the range [3σ, 1700σ]). For visualization purposes the v-scale has been highly compressed relative to that of Fig. 21 (identified by the magenta dashed lines). [SiVI] is a high-ionization line (≃205 eV) that traces the emission of high-velocity ionized gas in the outflow up to v − v_sys ≃ ±800 km s⁻¹ inside the CND region.
