Upper panel: fit of the NICMOS F222m light profile. The black continuous line represents the best-fit model. The dot-dashed line represents the profile of the compact component ( FWHM size) and the dashed line the extended component. The compact component is detected and identified with hot dust emission in NACO observations by Prieto et al. (2004). The spatial extension of the compact component is similar to that of the NICMOS PSF and therefore the first Airy ring is still visible. Lower panel: model residuals.
