Contour maps of the SiO (2–1) high-velocity (v< − 8 kms-1) emission from Gueth et al. (1998) convolved to the 
PACS resolution, the CO (16–15) line observed with PACS (Benedettini et al. 2012), H2 0–0 S(1) from Nisini et al. (2010b), and H2 1–0 S(1) from Caratti o Garatti et al. (2006), overlaid on the H2O (212 − 101) map at 179 μm (grey scale). In each panel the transition in contours is indicated.
