Book Description
Within the past few years very important additions have been made to the material at our disposal for an accurate determination of the positions and proper motions of the fundamental stars. These comprise Dr. Auwers' reduction of Bradley's observations, the Pulkowa catalogue of 1845, and the continuation of the Greenwich and Washington observations. It is not too much to say that this additional materials alone would suffice to furnish results far more accurate than any that could be obtained from the older data.
