CLEAN image of the synthetic EHT observations free from instrumental polarization. The full width at half maximum (FWHM) of the restoring beam is shown at bottom left. The 16 contour levels are separated in logarithmic scale and represent total intensity (peak of 1.28 Jy beam⁻¹; lowest contour of 1.3 mJy beam⁻¹); the blue color scale represents polarized intensity (peak of 0.36 Jy beam⁻¹) and the red lines represent the EVPA spatial distribution. The yellow crosses indicate the locations of the polarization intensity peaks, which are shifted with respect to those of Stokes ℐ. The green boxes indicate the extent of the polarization subcomponents used in the D-term fitting with the LPCAL approach.
