Magnetic field morphology over W43-MM1. The Stokes I emission is shown as colorscale, the dust, rician debiased, polarized intensity is shown in contours of 0.55, 1.3, 2.0, 2.7, and 3.5 mJy ﹩{\mathrm{beam}}^{-1}﹩. The magnetic field morphology is shown as pseudo-vectors at a significance of 3σ in green and 5σ in blue, where ﹩\sigma =93\;\mu \mathrm{Jy}\;{\mathrm{beam}}^{-1}﹩ corresponds to the noise in the polarized intensity image. The length of each pseudo-vector is normalized. Also, each pseudo-vector is plotted every half-beam, i.e., in steps of 8 and 4 pixels, where the beam is 13 × 7 pixels.
