Tapered JVLA 40–48 GHz continuum images of IRAS 16293–2422. The synthesized beam [θ_maj × θ_min = 3.′′ 3 × 2.′′ 6 (P.A. = –5.8°)] is shown in at bottom left. Contours present the Stokes I intensity. The Stokes Q and U dirty (i.e., not cleaned) images are presented in colors in panels a and b, respectively. Contours are 0.09 mJy beam⁻¹ (1σ, ~0.0066 K) × [3, 6, 12, 24, 48, 96, 192]. Color bars are in mJy beam⁻¹ units. Line segments are similar to those presented in Fig. 1, although we caution that the polarization position angles and percentages derived from Stokes Q and U dirty images are largely uncertain. In addition, in panel a, the SMA measurements at 341.5 GHz quoted from Table 4 of Rao et al. (2009) are overplotted as gray line segments which are bounded by blue lines. The baseline range covered by these SMA observations is 7–70 m, which corresponds to the uv distance range of 8–80 kλ.
