  Fix event generator to be in the target, not downstream

Due to a sign error, the events were generated around +4587 mm instead
of around -4587 mm. The call to GetFrameTranslation should have been a
call to GetTranslation, or various equivalent sign changes.

This was not a problem before since the target was centered at zero, and
so -0 is the same...
