The 1.3 mm continuum emission (black thicker contours) overlaid with the velocity-integrated intensity map of ¹²CO(2−1) outflow (red and blue contours). The black contour levels are at 3, 6, 9, 12, 15, 18, and 21σ (1σ is 0.002 Jy  beam^-1). The red and blue contour levels are 35, 50,..., 95% of the peak value. The synthesized beam is , PA = –58.9° (shown in the lower right corner). The black plus symbol marks the peak position of the continuum source. The blue and red plus symbols represent the positions of the extracted spectra in Fig. 4, respectively. The H₂O maser is shown by a filled triangle. The black and red open star symbols indicate the location of the infrared source IRAS 04579+4703 and a near-IR source detected by Varricatt et al. (2010), respectively. The blue and red dashed lines mark the directions of the NW and SE lobes of the H₂ knots (Varricatt et al. 2010), respectively.
