The 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. Volume 1 contains tables for selected stars for all latitudes, calculated for the epoch of 2010.0, it is intended for use for 5 years, when a new edition will be issued. Volume 2 for latitudes 0 - 40 and Volume 3 for latitudes 39 - 89 are permanent tables for integral degrees of declination. They provide sights for bodies with declinations within 30 north or south of the equator, which includes the Sun, the Moon, the navigational planets and many of the navigational stars. Sight Reduction Tables for Navigation are published in the USA as Sight Reduction Tables for Air Navigation Pub. No. 249, and in the UK as Rapid Sight Reduction Tables for Navigation AP 3270/NP 303.
