Residuals of the model on the HR 8799 (on the left column) and the RY lup (on the right column) datasets (square root stretch, colour bar: adu). a,b: raw data. c–f: zooms on the regions framed in (a,b). g–j: model prediction on the same regions of interest. k–n: residuals on the same regions of interest. o,p: statistics of the residuals. For comparison, Gaussian profiles of standard deviation σ = 47 adu (HR 8799) and σ = 23 adu (RY lup) are plotted. The region of interest framed in orange in (b) is the region detailed in Fig 6.
