It goes like this (and measurements are/were made in millimeters, such
that
1 mm = 1 ly). 

    |-----------------|       The central star (*) is in the center of
the
    |		      |    sector (0,0,0). Star 'a' let's say is 10 ly
below
    |		      |    the plane of the map, and star 'o' is 25 ly
(mm)
    |		      |    below the plane of the map (thus the vertical
    |		      |    difference between 'a' and 'o' is 15). Say
the
    |	     *	      |    *-a distance is 20, the *-o distance 40, and
the
    |	a	      |    a-o distance 45 (all in 'ly' or 'mm'). So if
you
    |		      |    want to know the distance between stars * and
'a',
    |		      |    simply calculate [sqrt(10**2+20**2)], or 22.4
ly
    |		o     |    (I rounded to the nearest 0.1 here). The
distance
    |_________________|    between 'a' and 'o' would be 47.4 ly. And the
			   distance from * and 'o' would be 47.2 ly.

Well...it works for me.  :-)
