Left: VLT/SPHERE coronagraphic R′ band Q_φ image of HD 100546 (Garufi et al. 2016). The image is r²-scaled with a correction only for the inclination of the disk. Center: the same Q_φ image with a correction for both the inclination and height of the flaring disk surface. Right: reconstructed r²-scaled total intensity image obtained by applying a correction for the degree of polarization on the Q_φ image. All images show a 2.′′0 × 2.′′0 field of view on the same linear color scale with equal minimum and maximum value. Orange corresponds to positive values, blue to negative values, and black is the zero-point. The 155 mas diameter coronagraph has been masked out. The contours of the left and center image show the radial distance from the central star to the point of scattering in the disk surface that is used for the r²-scaling. The contours of the right image show the local scattering angles that are used to calculate the phase function and estimate the total intensity.
