Paperback. Etat : New. Print on Demand. This book details the rigorous systematic analysis of polar distances and right ascensions of fundamental stars derived from observations made between 1862 and 1867. The author scrutinizes possible causes of systematic error and accounts for discrepancies in reported star measurements, including diurnal and annual inequality as well as the effects of changes in temperature and barometric pressure. The author also addresses the pointing accuracy of the zenith telescope. Extending earlier research, the author establishes that mean pointing accuracy did not vary by a measurable amount over the five-year span of observations. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781333735623_0
