A QUICK SYNOPSIS OF THESE FILES/FOLDERS [Planets_hXYZ] This folder holds the functions required to compute the full-precision VSOP87 heliocentric rectangular XYZ-coordinates of the planets from Mercury to Neptune. It also contains a template to create an XYZ-module for any of the given planets via a few simple search/replace operations. [standard_phases.zip] This folder contains 360 phase images that can be used to display the phase of a planet or moon. The images are labeled from 000 to 360 in terms of longitude from 0 to 360 degrees. [astronomy_lab.zip] This is the main module that serves as the common core of the project. It contains the general functions used to help compute and format the planetary position and other computations, [interface_1.zip] This is a base template interface that can be used to build a planetary almanac. It takes the date, time and optional delta-T and computes the JD number needed to begin most astronomical computations. This interface folder can simply be copied and renamed to the planet to which the program applies, such as "venus". [mecury.zip] This file contains a Mercury almanac program built from the above components. It computes the apparent geocentric position of Mercury for any given date and time (TDB) from 2000 BC to 6000 AD to a theoretical accuracy of within ±1 arc second within the range. [venus.zip] This file contains a Venus almanac program built from the above components. It computes the apparent geocentric position of Venus for any given date and time (TDB) from 2000 BC to 6000 AD to a theoretical accuracy of within ±1 arc second within the range. [mars.zip] This file contains a Mars almanac program built from the above components. It computes the apparent geocentric position of Mars for any given date and time (TDB) from 2000 BC to 6000 AD to a theoretical accuracy of within ±1 arc second within the range.
