This successful textbook by O. Montenbruck and T. Pfleger provides the reader with practical solutions to a variety of astronomical problems. The book includes both astronomical fundamentals and technical know-how for an implementation of high-quality software. Each chapter is carefully structured according to topic and closes with a listing of a relevant program, thereby facilitating use as a practical handbook. The enclosed diskette contains source texts of all programs for Turbo Pascal on IBM-compatible PCs or Pure Pascal on Atari ST/TT computers. For the new edition these programs have also been made accessible using Windows. Furthermore, an input file for the OCCULT program is now included containing the stars of the Zodiacal Catalogue by Robertson.
