An accurate astronomical ephemeris calculator
This program Development is an accurate in addition to fast astronomical ephemeris finance calculator in the period 3000 B . C . to AD 3000. That calculates heliocentric, geocentric, in addition to topocentric positions of typically the Sun (Earth), Moon, exoplanets, small bodies (asteroids, comets), and fixed stars inside ecliptical, equatorial, and side to side coordinates (including angular distinctions between two bodies), together with optional corrections for parallax and refraction; rectangular runs, velocity, apparent diameter, size, phase, lunar libration, orbital elements, differences for every these kinds of, and more. In add-on This program Development offers a riches of functionality: star graph and or chart generation, 3D-visualization of heliocentric and planetocentric orbits, conspiring ephemeris data, trying to find certain values, saving as Exceed, HTML, XML or text message files to export end result to spreadsheets, word cpus and web pages, making, and report generation (PDF, HTML, RTF). The ephemeris calculation is based after Steve Moshiers analytical ephemeris using trigonometric expansions regarding the earth and exoplanets and the lunar ephemeris ELP2000-85 of Chapront-Touzé in addition to Chapront for the moon phase, both adjusted to Plane Propulsion Laboratorys DE404. You can find further adjustments in This program Development, some optional, to JPLs more recent DE406, typically the most accurate long-term ephemeris. This program Development is fast. Together with an Athlon XP 2150 processor, 100 calculations regarding geocentric longitude, latitude, in addition to distance for the sunshine, moon, and all exoplanets take about 2 secs. A thorough documentation includes listar and graphic comparisons regarding calculations with HORIZONS epehemeris genarator.
