Polarized intensity image of NGC 4217 at L-band. The robust weighting parameter of clean was set to two, smoothed to a resulting beam size of 60″ × 60″, shown in the bottom left. Gray total intensity contours from D-configuration L-band smoothed to 60″, contours at 3 and 270σ levels with a σ of 136.7 μJy beam−1. Left: Polarization derived from StokesQandU maps with a σ of 35 μJy beam−1. The apparent magnetic field orientations, not corrected for Faraday rotation, are shown in white and clipped below 3σ. Right: Polarization derived via RM-synthesis with a σ of 32 μJy beam−1. The intrinsic magnetic field orientations corrected for Faraday rotation, are shown in white and clipped below 3σ.
