Suggested magnetic field line segments (i.e., B-segments) around IRAS 16293–2422 B. Line segments bound by white lines are the inferred magnetic field orientations from the Robust = 0 weighted JVLA 40–48 GHz images, and the color coding for them is the same as that in Fig. 1; those bounded by green lines are the inferred magnetic field orientations from the Robust = 2 weighted 40–48 GHz JVLA images and those bounded by blue lines are the inferred magnetic field orientations from the Robust = 0 weighted SMA 341.5 GHz images. More details of how this figure was generated are introduced in Sect. 4.2.
