Introduction
The Astrex library provides functions that perform astronomical calculations of various kinds.
This module provides high accuracy functions to calculate key date values for further astronomical calculations.
Calculates the Earth Magnetic field basing on local coordinates and (optionally) altitude. The calculations model is the WMM (World Magnetic Model).
This module exports one function that computes the Moon coordinates according to algoritm and QBasic source code from
Refraction can change significantly the apparent altitude of an object. The change depends solely on the altitude and is maximun on the horizon (objects may appear above the horizon when they are actually still below) and zero at the zenith
This module exports only one function to retrieve the current equatorial coordinates of the 9 planets (including Pluto) and of the Moon (via the Astrex.Astro.Moon module)
The module exports functions to convert from different coordinates systems
Common utilities to facilitate the astronomical calculations
This module provides functions to query for DeepSky objects recorded in the NGC and IC catalogs
Provides a GenServer to hold the local coordinates. This is useful for applications that are localized (e.g. telescope control) and makes possible to access the functions via the Astrex module, without supplying the local coordinates each time.
