Szego-Lobatto quadrature

Hello everybody

I have a question on the "Szego-Lobatto" quadrature rules, as follows:

I have eight points on a unit circle as follows
c1=(1,2); c2=(2,1); c3=(-1,2); c4= (-2,1); c5=(-2,-1); c6=(-1,-2);
c7=(1,-2); c8=(2,-1);

where a function f(c) is defined and its data is available.
I wish to integrate f(c) on the unit circle using a Sezego-Lobatto quadrature
rule (which should be the most accurate way of doing this job). But I don't
know how to compute the coefficients.

Would some one please just show me the way !
Many thanks in advance.
