Alcyone Astronomical Tables (AAT) is a collection of astronomical data in electronic form. It provides detailed information on various astronomical phenomena (conjunctions with the Sun, planetary conjunctions, oppositions, greatest eleongations, lunar phases, equinoxes and solstices, passages of aphelia and perihelia) covering the period 3000 BC to AD 3000. AAT offers additional functionality as printing, data export (Excel, HTML, ASCII, CSV), table sorting, and time range specification.
The calculation is based upon Steve Moshier's analytical ephemeris using trigonometric expansions for the earth and planets and the lunar ephemeris ELP2000-85 of Chapront-Touzé and Chapront for the moon, both adjusted to Jet Propulsion Laboratory's DE404.
Since all data are pre-calculated and saved in a database, all calculations are very fast. AAT can be used as a 'stand-alone program' and/or as an addition to Alcyone Ephemeris. The software runs under Windows ME/2000/XP/Vista.
