The Planet Coordinates module computes positional data for
|
||
|
|
any major solar system body, for any time and date and any
|
||
|
|
geographic location. Simply select the <guilabel>solar
|
||
|
|
system body</guilabel> from the drop-down list, and specify
|
||
|
|
the desired date, time, and geographic coordinates (these
|
||
|
|
values are preset to the current &kstars; settings). Then
|
||
|
|
press the <guibutton>Compute</guibutton> button to determine
|
||
|
|
the <link linkend="equatorial">Equatorial</link>, <link
|
||
|
|
linkend="horizontal">Horizontal</link>, and <link
|
||
|
|
linkend="ecliptic">Ecliptic</link> coordinates of the body.

There is a batch mode for this module. You must construct
|
||
|
|
an input file in which each line specifies values for the
|
||
|
|
input parameters (solar system body, date, time, longitude,
|
||
|
|
and latitude). You may choose to specify a constant value
|
||
|
|
for some of the parameters in the calculator window (these
|
||
|
|
parameters should be skipped in the input file). You may
|
||
|
|
also specify which of the output parameters (Equatorial,
|
||
|
|
Horizontal, and Ecliptic coordinates) should be calculated.
|
||
|
|
Finally, specify the input and output filenames, and press
|
||
|
|
the <guibutton>Run</guibutton> button to generate the output
|
||
|
|
file with the computed values.
