Photographic Measures of Double Stars. Volume 7, Part 1
Abstract
The photographic observations of double stars included in the present paper were made between October, 1946 and July, 1952, and are a continuation of the observations previously published by the writer. The present series of plates was taken with the Dearborn, Sproul and Yerkes refractors, and the method used in taking and measuring the plates is essentially the one first employed by Hertzsprung, which reduces to a minimum possible systematic and accidental errors.
