Notes. The coordinates of the multiple images of families A, B, and C are measured with SExtractor in the HST F160W image, while the positions of the multiple images of the E and F sources, whose continuum is not detected in HST, are taken as the brightest pixels in a narrow-band image centered around their Lyα emission lines.
