23 The Planet Coordinates module computes positional data for
24 any major solar system body, for any time and date and any
25 geographic location. Simply select the <guilabel>solar
26 system body</guilabel> from the drop-down list, and specify
27 the desired date, time, and geographic coordinates (these
28 values are preset to the current &kstars; settings). Then
29 press the <guibutton>Compute</guibutton> button to determine
30 the <link linkend="equatorial">Equatorial</link>, <link
31 linkend="horizontal">Horizontal</link>, and <link
32 linkend="ecliptic">Ecliptic</link> coordinates of the body.
35 There is a batch mode for this module. You must construct
36 an input file in which each line specifies values for the
37 input parameters (solar system body, date, time, longitude,
38 and latitude). You may choose to specify a constant value
39 for some of the parameters in the calculator window (these
40 parameters should be skipped in the input file). You may
41 also specify which of the output parameters (Equatorial,
42 Horizontal, and Ecliptic coordinates) should be calculated.
43 Finally, specify the input and output filenames, and press
44 the <guibutton>Run</guibutton> button to generate the output
45 file with the computed values.
