Contour map of blue- and red-shifted SiO(1–0) VLA emission superimposed on the 1.3 mm continuum emission as observed at high angular resolution by Beltrán et al. (2011) using a very extended SMA configuration (). The sources of the G24.78+0.08 cluster are labelled following Furuya et al. (2002) and Beltrán et al. (2004, 2011). The SiO emission was averaged over the velocity intervals (+80, +111) km s-1 and (+111, +132) km s-1 for the blue- and red-shifted emission, respectively. The 1σ rms of the SiO maps is 1.2 mJy beam-1 km s-1. Contour levels range from 5σ by steps of 3σ. The filled ellipse in the bottom-right corner shows the synthesised beam (HPBW): (PA = –15°).
