Maps of the EHV jets observed in SiO. Moment-0 maps are presented in color scale, in which continuum emission at 1.3 mm ispresented as black contours, both obtained with 12 m observations. SiO 4–3 map of HH211 integrated from −20 to −10 and from 10 to 20 km s⁻¹ with respect to v_sys, B1-c integrated from −70 to −40 and from 40 to 70 km s⁻¹ with respect to v_sys, and SMM3 integrated from −60 to −40 and from 20 to 35 km s⁻¹ with respect to v_sys.
