Self-subtraction residual maps for systems with tentative signs of asymmetries (HD 84870, HD 131488, HD 131835, and HD 218396). This figure presents data in the same manner as Fig. C.1. We present the contours of the rotation self-subtraction residuals in the left panel to highlight where these arise from in the image plane for HD 84870, of the minor axis self-subtraction residuals for HD 131488 and HD 131835, and of the major axis self-subtraction residuals for HD 218396.
