Astrophysical Quantities
"Astrophysical Quantities - APQ to many astrophysicists - has been an essential reference book from its first publication in 1955… Finally the fourth edition has been produced. It has taken 90 contributors to duplicate Allen's heroic single-handed efforts, but the result is well worth the wait. The new book is twice the size of the previous edition and contains many new topics and extended coverage of other topics that have increased in importance in the last three decades. … the new edition of APQ promises to be as useful as the old one, and most serious astronomers will want a copy…"C.R.Kitchin--This text refers to an alternateHardcoveredition.
