Continuum images of CX Tau from ALMA and VLA observations at different wavelengths, all obtained with Briggs weighting and robust 1. The full width at half maximum (FWHM) of the synthesized beam is indicated by the ellipse in the bottom left corner of each image. The rightmost panel shows a zoomed image of the ALMA 1.3 mm observation from Facchini et al. (2019) which has the highest angular resolution. Contours indicate the [5, 10, 20, 40]σ levels.
