Images obtained at 1.87μm (F187N; top row) and 4.80μm (F480M; bottom row) after subtraction of the stellar PSF using roll subtraction (first column), and after additional subtraction of the best outer-disk model using the negative fake disk technique (second column; details in Appendix B). The third column shows the residuals after both disk and planet subtraction, using the parameters found with NEGFC (Appendix C). The circles indicate the predicted location of the two protoplanets based on the orbital fits presented in Wang et al. (2021b).
