<h1>ELP/MPP02 Lunar Ephemeris (JavaScript Version)</h1>
<br />
<p>ELP/MPP02 is a semi-analytic solution for the lunar motion developed by J. Chapront and G. Francou in 2002. It is an improvement of the ELP2000-82B lunar theory.</p>
<p>Source paper: <i>The lunar theory ELP revisited. Introduction of new planetary perturbations</i> by J. Chapront and G. Francou, <a href="http://adsabs.harvard.edu/abs/2003A%26A...404..735C" target="_blank">Astronomy and Astrophysics, v.404, p.735-742 (2003)</a>.</p>
<p>This page provides a JavaScript version of the code. It is generated by my C++ code <code>ElpMpp_JavaScript.cpp</code>, available on <a href="https://github.com/ytliu0/ElpMpp02">my GitHub page</a>. My C++ code is based on the authors' FORTRAN source code and data files on ftp://cyrano-se.obspm.fr/pub/2_lunar_solutions/2_elpmpp02/.</p>
<p>This page provides a simple platform to calculate the ELP/MPP02 series. It is intended for code test.</p>
