0023 This module converts between <link linkend="equatorial">Equatorial
0024 coordinates</link> and <link linkend="ecliptic">Ecliptic
0025 coordinates</link>.  First, select <guilabel>Date and time:</guilabel>.
0026 Then, fill in the coordinate values in either the <guilabel>Ecliptic
0027 Coordinates</guilabel> or <guilabel>Equatorial Coordinates</guilabel>
0028 section.  Alternatively set the equatorial coordinates by selecting an
0029 object using the <guilabel>Find Object</guilabel> dialog.
0030 Then the complementary coordinates will be filled in.
