Another theory, with pictures and should be fairly easy to position in space:

The above shows the UP clue superimposed over the entire Merope system. I centered the grid on Merope 5, and pointed the line in the bottom right quadrant to line up with the system star. Then I scaled the view down:

I scaled the clue so that the circle matches Merope 5's rings and the top left arc happens to line up with the orbit of the first planet/moon. Coincidence?
So, assuming the symbols in the corners are binary, and they are defining a series of steps, then I have
1) aligned the two stars as step 1.
2) scaled the clue to match a celestial feature, and the top right arc becomes concentric with the first orbit as step 2
then:
3) Look at the 2nd orbit? for step 3.
4) On this side? Which coincides with the intersection of the orbit lines of the Merope 5 star and planet/moon 2. ... step 4
Should be easy to go there and wait for a USS or something?
If no one else does, I will fly to Merope again, and science this myself, next time I get to log on.
