Fig. 3
Observed radial surface-brightness distribution on HD 142527 L′ PSF-reference subtracted image with a scaling factor of 2.2 towards the extended part of the disk (47−227 deg). Dashed lines correspond to fitted straight line between 0.9′′ and 1.3′′ for PA = 47 deg and between 1.2′′ and 1.8′′ for PA = 227 deg.
