Comparison of the best-fit solutions for y = −80 mas and y = 0 mas for the K3 dataset. a) Image of the unconvolved best-fit model disk with y = −80 mas at logarithmic stretch. b) Same for y = 0 mas. c) S/N map of the residual image after subtracting the ADI-processed best-fit model image with y = −80 mas from the ADI-processed data at a linear stretch of ±5σ. d) Same for y = 0 mas. e) Difference of the images d)–c) at a linear stretch of ± 2σ. The χ² of the y = 0 mas model exceeds that of the y = −80 mas model by 6.0 Δχ².
