This module converts between <link linkend="equatorial">Equatorial
|
||
|
|
coordinates</link> and <link linkend="ecliptic">Ecliptic
|
||
|
|
coordinates</link>. First, select which coordinates
|
||
|
|
should be taken as input values in the <guilabel>Choose Input
|
||
|
|
Coordinates</guilabel> section. Then, fill in the corresponding
|
||
|
|
coordinate values in either the <guilabel>Ecliptic
|
||
|
|
coordinates</guilabel> or <guilabel>Equatorial coordinates</guilabel>
|
||
|
|
section. Finally, press the <guibutton>Compute</guibutton> button,
|
||
|
|
and the complementary coordinates will be filled in.

The module contains a batch mode for converting several coordinate
|
||
|
|
pairs at once. You must construct an input file in which each line
|
||
|
|
contains two values: the input coordinate pairs (either Equatorial
|
||
|
|
or Ecliptic). Then specify which coordinates you are using as input,
|
||
|
|
and identify the input and output filenames. Finally, press the
|
||
|
|
<guibutton>Run</guibutton> button to generate the output file,
|
||
|
|
which will contain the converted coordinates (Equatorial or
|
||
|
|
Ecliptic; the complement of what you chose as the input values).
