Alcyone Astronomical Tables 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 Moshiers 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 Laboratorys DE404 (see www.moshier.net).
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. |
