Notes. The SCUBA 850 m data and the 1.2 mm data are taken from Di Francesco et al. (2008) and Beuther et al. (2002), respectively. ⁽¹⁾ IRAS flux; ⁽²⁾ artifact (see Fig. 1); ⁽³⁾ Beuther & Steinacker (2007); ⁽⁴⁾ because the source is embedded in absorption filament, we selected smaller aperture just covering the emission source; ⁽⁵⁾ because of absorption close to the source, here we applied PSF photometry based on the template by Poglitsch et al. (2010); ⁽⁶⁾ we corrected for the mapping artifact visible around the source in Fig. 1.
