Radio continuum emission at 6 cm (MAGPIS; White et al. 2005) of the area mapped using ASTE. The green contours represent the HCO⁺J = 4–3 emission distribution integrated between 58 and 67 km s^-1. The black contours were taken from the paper of Wilner et al. (1996) and represent the HCO⁺J = 1–0 emission distribution integrated from 58 and 67 km s^-1. The box indicates the area observed by Wilner et al. (1996). The numbers show the five HCO⁺J = 1–0 clumps. The red circles represent the YSO candidates shown in Fig. 13.
