Excerpt from On the Right Ascensions of the Equatorial Fundamental Stars and the Corrections Necessary to Reduce the Right Ascensions of Different Catalogues to a Mean Homogeneous System
The first column shows the differences independently deduced; the second their values when each is diminished by a constant so as to make their sum zero.
The smallness of this result indicates that the periodic error, if it exists at all, must be very small, and it ought to be smaller still in the catalogue of 1864, which includes still another revision.
