The Rotation of the Celestial Equatorial System with the so-called “Non-Rotating Origin”per derives the analytical relation between the traditional and the alternative equatorial systems by means of their rotation vectors. Under the assumption of a regular precession of the mean celestial pole, the motions of the rotation vector and the first axis of the alternative mean equatorial sys

The Generalized Mollweide Projection of the Biaxial Ellipsoidhe class of pseudocylindrical mapping equations of E. (semimajor axis A, semiminor axis B) it is shown by solving the general eigenvalue problem (Tissot analysis) that only equiareal mappings, no conformai mappings exist. The mapping equations which generalize those from S. to E. lead under the equi
