Table B.1
Coordinates with respect to the center of our image for the peak submillimeter emission of PDS 70 b and c and their L4 and L5 Lagrangian points. July 2019 is the epoch of the long baseline observation used in the composed image of this work. February 2026 and November 2028 are the minimum predicted dates to measure the co-orbital motion in PDS 70 b and c orbits, respectively.
