Comment:

 I found the missing factor pi. This factor is actually present in the
 (unnumbered!) equations in the Driscoll&Healy paper. In my tests, I left
 it out because I implicitly assumed that theta ranges [0...1], whereas of
 course it ranger [0...pi]. This made the results too large by a factor of
 pi.

 There was also an error in the index bounds. Driscoll&Healy want a point
 on the equator, which corresponds to even ntheta, not odd ntheta as
 previously in the code.

 Applied.
