Maps of the outflow cavity wall tracers toward SMM3 and B1c, with the low-velocity outflow map for reference. Top: moment-0 maps toward SMM3 of CO 2–1, c-C₃H₂ 6_1,6 –5_0,5, and ¹³CS 5–4 obtainedin band 6 at 0.′′5 resolution and CN 1–0 in band 3 at 3′′ with continuum emission at the same band and the resolution shown as black contours. Bottom: moment-0 maps toward B1c of SO 6₇–5₆, C₂H 3_2.5,3 –2_1.5,1, and H¹³CO⁺ 3–2 obtainedat 0.′′5 and CN 1–0 at 3′′ resolution with continuum emission at the same band and the resolution shown as black contours. The emission is integrated from −5 to −1 km s⁻¹ and from 1 to 5 km s⁻¹ with respect to v_lsr. Outflow directions and delineated cavity walls are shown in C₂H and C₃H₂ maps.
