IRAS 16293-2422 B observed at ALMA bands 6 and 3 and VLA bands Q, Ka, and Ku (from left to right). The cyan vectors represent polarization E-vectors (masked out below 3σ_I and 3σ_Q), and the scale bar indicates a 2% polarization fraction. The continuum data at 1.3 and 3 mm were presented by Zamponi et al. (2021), and the 1.3 mm polarization observations were presented by Sadavoy et al. (2018). The polarized continuum observations at 7 mm were obtained from Liu et al. (2018). The 9 mm and 18 mm continuum observations are presented for the first time by this work. The angular resolution of the observations are as follows: 0.114″ × 0.069″ at 1.3 mm (0.18″ × 0.09″ for polarized data); 0.048″ × 0.046″ at 3 mm; 0.39″ × 0.24″ at 7 mm; 0.12″ × 0.05″ at 9 mm; and 0.23″ × 0.09″ at 18 mm.
