Radial SB profiles of the west and east disc sides in the J and H band. All data points show the disc magnitude measured in square 0.25′′× 0.25′′ (20 × 20 pixels) apertures, centred on the disc major axis, relative to the stellar magnitude in the corresponding filter. Circles indicate the relative magnitude of the total intensity of scattered light (Stokes I) and diamonds mark the magnitude of the polarized flux (Stokes Q_φ). Errors are calculated as a standard deviation of the flux distribution in the concentric annuli.
