(a) From top to bottom: IRDIS science image in BB_H, best GRaTer model with the parameters i = 88°, αout = −6, αin = 2, R0 = 140 au, g1 = 0.70, g2 = −0.4, w1 = 0.80, h = 0.020, KLIP processed image for the corresponding GRaTer model, and the residual image. All the images are cropped at 3″ × 0.5″ and rotated to 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, 0.25].
