Left panel: continuum map at 0.87 mm after unsharp masking compared with the orientation of the linear polarization vectors at 0.87 mm (Bacciotti et al. 2018). The orange ellipse in the bottom left corner indicates the synthesized beam of the 0.87 mm continuum. Right panel: RGB image showing the continuum at 1.3 mm after unsharp masking (in red), H₂ CO 3_1,2 − 2_1,1 (in blue), and CS 5−4 (in green).The blue, red, and green ellipses in the bottom left corner indicate the synthesized beam for H₂ CO, continuum, and CS, respectively.
