Fig. 1
Top panel: EVPAs as a function of wavelength squared for 3C 273 over the ALMA 1 mm band. The uncertainties in the EVPA are obtained through MC simulations described in Appendix A. The dashed line is a linear fit to the data giving RM = (5.01 ± 0.04) × 105 rad m−2 and intrinsic EVPA of −108°. Bottom panel: residuals of the fit with MC uncertainties shown in gray.
