Surface brightness as a function of the scattering angle extracted in concentric annulii, accounting for the inclination and position angle of the disk, with increasing deprojected stellocentric distances r (in arc-sec). For clarity, the profiles have been offset and the horizontal lines show the zero point in the top panel, while no offset has been included for the bottom panel to best compare the different profiles. The fainter lines in the top panel show the best-fit with an HG-phase function (the ɡ values are reported in the legend). The gray-shaded areas show the scattering angles that are not accessible to us for an inclination of 82°.
