Precise astronomical measurements from a landmark parallax study. This volume presents the solar parallax determination using photographs of Eros taken with the Crossley reflector at Lick Observatory, detailing the observing program, measurement techniques, and reduction methods that underpinned the effort.
The work covers the practical challenges of photographic astrometry, the selection and measurement of plates, and the complex reductions needed to derive parallax and ephemeris corrections. It includes a thorough account of the measuring engine and its role in producing stable, accurate plate data, along with the historical context of collaboration between multiple observatories and researchers.
Ideal for readers interested in the history of astronomical measurement, propitiating large-scale observational campaigns, and the hands-on work behind determining fundamental constants.

Paperback. Etat : New. Print on Demand. This book documents Charles Perrine's investigation into the astronomical unit, as defined by the distance from the Earth to the Sun. The study is remarkable for its precision and startling revelations. Perrine's work began following the untimely passing of his revered mentor when he was tasked with managing all duties associated with the Crossley reflecting telescope. His experience, enthusiasm, and competence through this trying period were central to successfully securing the observational material that the project required. The author used photography for determinations of the highest precision, presenting a plan of reduction designed to detect errors peculiar to photographic methods. The national and international collaboration and data sharing that were central to the author's work are discussed, and the influence of his approach to data collection and analysis on the development of astronomy is explained. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
