This is the standard set of tables designed for marine navigation. Although there are 6 volumes in a set, only those pertaining to the latitudes anticipated need be obtained. Their tabular data, being purely mathematical results, never go out of date. The latitudes listed for the Volumes work for either northern or southern hemisphere.
Because of the high price and spotty availabliity of the Government editions, these are reprinted 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.
*Used by most navigators.

Comments about #249 Aviation Table, Volume 1 for Selected Stars, Epoch Edition*:
Sometimes there are bright stars above 30 Degrees declination that are useful for navigation. They are not detailed in Vols 1 or 2. Plus there is a ton of good information on stars.
