Left: observed SED (black diamonds) and SED of the best-fit temperature-gradient model (Table 4). The total SED (red line) consists of the stellar flux (Kurucz model, black dashed line) and the flux of the temperature-gradient disk (black solid line). Right: two-dimensional intensity distribution of the best-fit model at 2 μm. The color-scaling is linear in arbitrary units. The star is not displayed.
