Planets.tclsh
Calculates very rough RA, DEC, Az, El, Rise, Set, and Transit times 

(in UT) for the planets, the Sun and the Moon.



Optional arguments:

   -h or -help  Brings up this help page and all other options are ignored

   -MJD         Modified Julian Date.  If not specified, assumes the 

                current time

   -Lat, -Long  Latitude and Longitude of the observing position.  Defaults

               
are 38.433121 and -79.839835, the location of Green Bank

   -elevLimit   Elevation limit in degrees for defining a rise or set time.

                Default=5.



The accuracy of the topocentric coordinates for Neptune and Uranus is ~0.5

degrees and the accuracy for all other objects is ~0.1 deg.  The accuracy

of the rise, transit and set times is about 15 min.
