| Abstract: |
A difference between the use of nonrotating origin in astrometric VLBI and the classical approach is shown to exist at the level of a few milliarcsec. The difference is due to the terms which are generally neglected when considering the equation of equinoxes in the classical representation of the earth angle of rotation. |
