From top to bottom: IRDIS science image in BB_H, best GRaTer model with the parameters i = 88.5°, αout = −6, αin = 10, R0 = 130 au, g = 0.60, h = 0.020, KLIP processed image for the corresponding GRaTer model, and the residual image. The images are cropped at 3″ × 0.5″ and rotated at 90° – PA. The science image, KLIP processed image, and the residual image are scaled linearly in the range [ − 1 × 10−5, 1 × 10−5 ] and the GRaTer model is scaled linearly in the range [0.0, 0.5].
