+% Two solutions may be considered for
+% this construction. The first (and the
+% one which is done here) is to put the
+% two centers of circles at a predeterminated
+% distance $a$ from each others (namely $a = 4u$)
+% and do the construction hoping that edges
+% will fit the right bound.
+% The second one consists in calculating that
+% distance $a$ to make sure that edges will lie
+% on the right bound (the calculations are shown
+% commentated). The problem with this method
+% is that there is no control of the clear part's
+% width of the drawing. Moreover, when the inner
+% radius become too small there is no more solution
+% to that problem (see below). 
+%
+%% The actual width of the drawing must be 10u.
+%% The problem is to calculate the distance
+%% between the two centers to make it work.
+%% Alas when the two radius are too far from
+%% each over, this problem has no solution.
+%%
+%% 6.5u = radius of great circle.
+%% 3.5u = 10u-6.5u = (inner width)-radius.
