FOREWORD
Rapid Sight Reduction Tables for Navigation consist of three volumes of comprehensive tables of altitude and azimuth designed for the rapid reduction of astronomical sights. These volumes were originally entitled Sight Reduction Tables for Air Navigation. The modified title and change in emphasis of the explanation, examples and auxiliary tables are due to theire popularity for marine navigation. However, the format and star selection of main tabular material remains unchanged.
The present volume(Volume 1) contains tables for selected stars for all latitudes, calculated for the epoch of 2015.0, and replaces the previous edition calculated for the epoch of 2010.0; it is intended for use for about 5 years, centered about 2015.0. Volume 2 for latitudes 0º~40º and Volume 3 for latitudes 39º-89º are permanent tables for integral degrees of declination. They provide sights for bodies with declinations within 30ºnorth or south of the equator, which includes the Sun, the Moon, the navigational planets and many navigational stars.
