Polarization data toward Hub-N (top panel) and Hub-S (bottom panel) of the IRDC G14.2. Red segments depict the magnetic field (Nyquist sample) observed with the CSO at 350 μm obtained by rotating polarization vectors by 90°. The width illustrates segments above 3σ_p (thick segments) and between 2σ_p and 3σ_p (thin segments). Only segments over 15%/25% in Hub-N/Hub-S of Stokes I peak intensity are shown. Blue segments depict the magnetic field obtained from near-infrared (H-band) observations (Santos et al. 2016). Contours show the CSO 350 μm dust continuum emission (Busquet et al. 2016; Lin et al. 2017a,b). Contour levels are 2, 4, 6, 8, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 times the rms noise (~ 80 mJy beam⁻¹). The CSO beam (~10″) is shown in the bottom left corner of each panel. The yellow star (top panel) depicts the position of IRAS 18153-1651.
