Azimuthally averaged radial profile of the disk, measured after r²-scaling of the images: negative radii correspond to the east (faint outer disk) side of the image, with the profile averaged over position angles of 20–220°; positive radii correspond to the west (bright outer disk) side of the image, with the profile averaged over position angles of 240–360°. The gray shaded area shows the region covered by the coronograph. Profile has been offset vertically by a factor 1.5, and the errorbars shown for the J-band 2016 data are representative of all three epochs.
