Mean and Apparent Place Computations in the New IAU System. II. Transformation of Mean Star Places from FK4 B1950.0 to FK5 J2000.0 Using Matrices in 6-Space
A 6 x 6 matrix method for transforming a catalog mean place from epoch and equinox B 1950.0 on the FK4 system to epoch and equinox J2000.0 on the FK5 system is described. A step-by-step comparison is made between the matrix method and the classical spherical formulas.
