Azimuthal surface brightness profiles obtained around DR Tau using the IRDIS polarized data at separations of 0.3′′ (upper left panel), 0.5′′ (upper right panel), 0.7′′ (bottom left panel), and 0.9′′ (bottom right panel). The black arrow in the top left panel indicates the position of the peak due to the compact feature. The error bars in the 0.3′′ plot are barely visible due to the higher flux scale in that plot with respect to those obtained at larger separations.
