Moment-0 map in color scale and 1.3 mm continuum in contours of B1-c. CO 2–1 E_up =48 K and CH₃OH 4₂ –5₁ E_up =60 K moment-0 maps obtained in band 6 at 0.′′5 resolution. Sputtering product emission toward SMM3 in band 3 at 3′′ resolution. CH₃CHO 6_1,6,1 –5_1,5,1 E_up =21 K, HNCO 5_0,5–4_0,4 E_up =16 K, and CH₃CN 6₀ -5₀ E_up =19 K and CH₃OCHO 9_5,5 –8_5,4 E_up =43 K. Moment-0 map integrated from -10 to 10 km s⁻¹ with respect to v_sys for SO and from -2 to 2 km s⁻¹ with respect to v_sys for the other molecules.
