Fig. 6

Comparison between the continuum image of IK Tau (white contours at (1, 3, 5, 10) × 0.141 mJy beam−1 (3σrms)) and the molecular emission of HCN(4–3) (left panel) and NaCl(26–25) (right panel) showing the co-location of the dust continuum emission and the molecular emission. The molecular emission is shown for a specific frequency not corrected for the vLSR as given in the upper right corner of each panel.
