Colorscale of the nonthermal degree of polarization at C-band with the intrinsic magnetic field orientation (line segments of equal length) at C-band. Values were calculated at pixels where the polarized intensity is larger than 2σ and the synchrotron intensity is larger than 3σ (Mora-Partiarroyo et al. 2019). C-band polarization angles (VLA D-configuration) were calculated at pixels where the polarized intensity is larger than 5σ. All data plotted have an angular resolution of FWHM. Grey contours correspond to the 5.99 GHz total power emission (VLA + Effelsberg) are at 45 μJy beam⁻¹ × (3, 6, 12, 24, 48, 96, 192, 384).
