Alcyone Ephemeris is an accurate and dissolute astronomical ephemeris calculator cover the flow 3000 BC to AD 3000. It calculates heliocentric, geocentric, and topocentric positions of the Sun (Earth), Moon, planets and reconditioned stars in ecliptical, equatorial, and horizontal coordinates (including angular differences between two bodies), with optional corrections for parallax and refraction; rectangular coordinates, velocity, apparent diameter, magnitude, phase, lunar libration, orbital elements, differences for completely of these, and more. In summation Alcyone Ephemeris offers a wealth of functionality: plotting ephemeris data, searching for specific values, scripting to spell programs for more complex computations, saving as HTML or Excel files to export output to spreadsheets, password processors and web pages, and printing. The ephemeris reckoning is based upon Steve Moshier's analytical ephemeris using trigonometric expansions for the earth and planets and the lunar ephemeris ELP2000-85 of Chapront-TouzГ© and Chapront for the moon, both adjusted to Jet Propulsion Laboratory's DE404. There are boost adjustments in Alcyone Ephemeris, some optional, to JPL's more recent DE406, the most accurate long-term ephemeris. Alcyone Ephemeris is dissolute. With an Athlon XP 2000+ processor, 100 calculations of geocentric longitude, latitude, and distance for the sunbathe, moon, and completely planets take around 2 seconds. The ephemeris curriculum itself is also compact, around 20 mgb, compared to most 200 mgb of data files for DE406. A comprehensive documentation includes tabular and graphic comparisons of calculations with HORIZONS epehemris genarator.
