NIRCam images of PDS 70 obtained in the F187N (top row) and F480M (bottom row) filters using our iterative PCA algorithm. The second and third columns show the images obtained after subtraction of our outer-disk model and after further subtraction of protoplanets b and c, respectively. The major and minor axes of the disk are indicated in the first column with solid and dashed lines, respectively. The dashed circles indicate the predicted locations of protoplanets b and c based on the orbital fits in Wang et al. (2021b) and the location of candidate d based on the orbit suggested in M19. The astrometric measurements for d (blue dots) are compared to our new estimated astrometry (solid circle) in panel c. The units are MJy sr−1.
