Multifrequency images of 3C 111 at 15 GHz (VLBA, from the MOJAVE programme), 43 GHz (VLBA, from the Boston-Blazar-Group programme) and 86 GHz (GMVA) to highlight the association of J1, J2, J3 and J4 with the 15 GHz counterparts (B1, B2, B3, B4) reported in Beuchert et al. (2018). In this image, we corrected for the core shift between 15 GHz and 43 GHz by applying a shift to the 15 GHz image (ΔRA = −0.22 mas, ΔDec = −0.09, Beuchert et al. 2018). The coordinates of the components are listed in Table A.3.
