Top-Left: composite aperture-synthesis image of HD 62623. The convolving beam of 1.75 × 2.76 mas is shown in the lower-left box at the same scale. The dashed line represent the polarization measurement from Yudin & Evans (1998). Top-Right: our best-fit model plot at the same scale and convolved with the same beam. Bottom-left: line images of HD 62623. The line intensity is plot as colours for different gas velocities. The intensity in the continuum is plot as gray contours (80%, 40%, 20%, 10%, 5%, 2.5% and 1.25% of the peak intensity). Bottom-Right: our best-fit model line images with the same representation and the same convolving beam.
