Caption: Figure 4.

This figure illustrates the relative proper motion of HH 689d and 689e. Top: the F555W image from ACS/WFC with PDS 144 N & S on the left of each frame, and the location of HH 689d and 689e is indicated in each frame by , middle: the F606W image from ACS/WFC, and bottom: the F606W image with the F555W image subtracted to show the relative proper motion of HH 689e and HH 689d over the 3.89 year baseline.
