Abstract
RUTHERFURD MEASURES OF PLEIADES.—In the Contributions from the Observatory of Columbia University, No. 17, Mr. Harold Jacoby furnishes a revised discussion of the series, of measures made by Rutherfurd of photographs of the Pleiades group dating from the years 1872 and 1874. The results of the first investigation were published in 1892, and are slightly modified in the present paper. Special reductions have been made to test the possibility of there being systematic errors arising from some form of optical distortion of the object-glass, and comparisons are given of heliometer and photographic measures. The final data are collected to form a catalogue of seventy-five stars in the cluster.
