These observations achieve a resolution of 4 au (3.8 mas), an rms noise of 66$\\mu$Jy/beam, and reveal an asymmetric ring between $\\sim$20-40 au with largely optically thin dust continuum emission. This ring is well fit by two concentric and overlapping Gaussian rings of different widths and a Vortex.
