About Herfkens 1949: I checked the equations and they are basically correct, except for some typos. Note that his beta is our delta cos(lambda) in the linearized equations. On page 12, Eq. (28), cot(beta) should be cot(alpha). There are a missing term and misplaced brackets on p.13, and the subscript of b_5 is missing in Eq. (34) on page 14. The coefficients on page 15 agree with ours.
