ALMA band 6 full-polarization image of PKS 1830−211. Contours represent Stokes I and are given in logarithmic scale, running from 2% to 90% of the peak intensity (2.34 Jy beam⁻¹); the polarized intensity is color-coded (see scale at top); the thick lines represent the EVPA, with lengths proportional to fractional polarization (the peak of 14% is located at the SW image). The scale of the fractional polarization, m, is given by the line in the top right corner; the full width at half maximum of the CLEAN beam is shown in the bottom left corner.
