Fig. 3
Two different disc reductions: cADI-disc (top) and PCA-disc (bottom). The black arrow shows the apparent midplane, has a position angle of 29° (equal to that of the main disc), and a total length of 6′′. The colour scale is identical for both images but not linear (square root). The green square marks the position of the star and the green circle has a radius of 0.4″.
