Continuum maps at millimeter wavelengths. Top left: ALMA map at 0.87 mm. Top right: NOEMA map at 1.1 mm. Bottom left: ALMA map at 2.2 mm. Bottom right: VLA map at 7 mm. The light gray contours in the bottom right panel depict 5σ continuum emission at 2.2 mm from our ALMA map. The gray dashed line marks the position of the centimeter jet detected by Rodríguez et al. (2014). The green star marks the position of the tentative protoplanet proposed by Currie et al. (2022). The synthesized beam is shown in the bottom left corner of each map. Contour levels in the 0.87, 1.1, and 6.8 mm maps are 5, 10, 25, and 50σ. The 2.2 mm map only shows 5, 10, and 25σ levels. The map of the VLA emission at 7 mm also includes 3σ contour levels. In all maps, the color bar indicates flux in mJy beam⁻¹.
