Left: radial profiles after RDI of TW Hya, AS 209, Elias 2-24, and the reference star β Lib in logarithmic scale. The profiles were computed from RDI data. Separation is expressed in arcseconds, and the flux is normalized to the stellar peak intensity. Right: residuals of the radial profiles after exponential fitting, with an incremental offset of 2 applied to each curve to avoid overlap. A dashed line indicates the new zero level of the residuals and the arrows indicate the observed gaps.
