Abstract
The relative orientations of radio and optical axes of radio galaxies have been examined on the basis of combined material from several smaller samples. Rotation axes of some radio galaxies have been redetermined assuming that the published measurements refer to rotational motions only. It is found that the rotation axis is quite different from those previous determinations, where rotation-expansion models were used. In particular, the correlation between radio source axes and rotation axes disappears when the allowance for expansion is dropped. No statistically significant correlation between optical major axes of the galaxy image and radio source axes is found when all existing measurements, now exceeding 140, are combined.
