Continuum image of N30, with the red- and blueshifted 342.88 GHz CS line transition J = 7− 6 shown in contours. As with the H₂CO line, CS shows red- and blueshifted emission along the same outflow axis. The blueshifted emission shows some extended emission further out to the northeast, while the redshifted emission is slightly more concentrated than for H₂CO. Here, the velocity ranges extend to ±15.6 km s⁻¹ from the systemic velocity of 8.75 km s⁻¹. Beam sizes and contour levels are as in Fig. 3.
