23 This module converts between <link linkend="equatorial">Equatorial
24 coordinates</link> and <link linkend="ecliptic">Ecliptic
25 coordinates</link>. First, select which coordinates
26 should be taken as input values in the <guilabel>Choose Input
27 Coordinates</guilabel> section. Then, fill in the corresponding
28 coordinate values in either the <guilabel>Ecliptic
29 coordinates</guilabel> or <guilabel>Equatorial coordinates</guilabel>
30 section. Finally, press the <guibutton>Compute</guibutton> button,
31 and the complementary coordinates will be filled in.
34 The module contains a batch mode for converting several coordinate
35 pairs at once. You must construct an input file in which each line
36 contains two values: the input coordinate pairs (either Equatorial
37 or Ecliptic). Then specify which coordinates you are using as input,
38 and identify the input and output filenames. Finally, press the
39 <guibutton>Run</guibutton> button to generate the output file,
40 which will contain the converted coordinates (Equatorial or
41 Ecliptic; the complement of what you chose as the input values).
