These tables were designed for air navigation where weight and space are at a premium, however, they are very popular with sailors too due to the fact that Vol. 1 offers a speedier way to compute stars.
The way the 6 volumes of 229 were combined into this 3 volume set is this: volumes 2 & 3 cover all latitudes, but work only for declination's from 0° to 29° north or south. This covers the sun, moon, planets, and only those stars whose declination's fall into this range. Volume 1 contains some stars (whose declination's may be more than 29°) that are pre-selected for optimum viewing and direction.
This volume is applicable for an 8 year period, centred on its Epoch date. The only drawback to this arrangement, is that it is possible that a star may be observed that is not one of the pre-selected ones, and whose declination is more than 29° north or south. This star, if observed on some unlikely occasion, say through a break in the overcast, could not be computed using the 249 tables. Nevertheless this remains the most popular tabular system in use. Due to the high price and spotty availability of the Government editions, Celestaire have reprinted these as Commercial Editions from official Government electronic files. They are economical, and sized at 90% of the originals. They have soft instead of hard covers and their smaller size of 8.5 x 11 inches is easier to carry and store.
