Top row: fiducial image of the continuum observations of HD 126062 reconstructed using tclean with natural weighting (left). Gaussian ring model derived from the MCMC fit to the visibilities (middle). Residual image following the subtraction of the model from the data, restored using the same imaging parameters as the tclean image (right). Bottom row: same as the top row, except tclean images have been reconstructed with a uvtaper of $1_{\cdot }^{\mathrm{\prime }\mathrm{\prime }}5$ applied. Contours are drawn in the tclean and residual images at −3, 3, 4×σ_im, where σ_nat = 25 μJy/beam and σ_taper = 40 μJy/beam. Negative contours are shown as dashed lines.
