Moment zero maps of the lines of SO 6₇−5₆ (E_up = 47.6 K), HNCO 12_0,12−11_0,11 (E_up = 82.3 K), and NH₂CHO 13_1,13 − 12_1,12 (E_up = 91.8 K) (from left to right) for B1-c (top row) and S68N (bottom row) in the Band 6 data. The images are made by integrating over [−10, 10] km s⁻¹ with respect to V_lsr. The black contours show the continuum in levels of [15, 30, 45, 60, 75, 90, 105] σ_cont with a σ_cont of 0.2 mJy beam⁻¹ for B1-c and [30, 45, 60, 75, 90, 105, 120] σ_cont with a σ_cont of 0.09 mJy beam⁻¹ for S68N. The beam size is shown at the right-hand side of each panel. SO traces the extended outflow, while the other two molecules show compact emissions. The approximate directions of the blueshifted and redshifted emission of the outflow are shown with blue and red arrows.
