Colorscale of the Faraday depth obtained from C-band (VLA D-configuration) data, together with the intrinsic magnetic field orientation (line segments of equal length) at C-band. Faraday depth and polarization angles were calculated at pixels where the C-band polarized intensity is larger than 5σ. All data plotted have an angular resolution of FWHM. Black contours corresponding to the 5.99 GHz total power emission (VLA + Effelsberg) are at 45 μJy beam⁻¹ × (3, 6, 12, 24, 48, 96, 192, 384), refer to Mora-Partiarroyo et al. (2019) for details concerning the total intensity emission. The blue rectangular box indicates the region from which the Faraday depth profile shown in Fig. 6 was extracted.
