 The position of the planets are computed using the JPL ephemeris or if no file are found for the current date, the library [[http://www.moshier.net/|plan404 by Steve Moshier]] that allows for computation from -3000 to +3000 with a precision better than one arc second.\\
-By default an extract of DE405 valid between 2000 and 2050 is supplied with the program. So the first thing to do if you want long term high precision planet position is to install a [[ftp://ssd.jpl.nasa.gov/pub/eph/planets/Linux/|full DExxx]] file.\\

 DE431 is recommended if you can afford the 2.5GB download. With this file you can compute precise planet position and nutation between -13000 and +17000.
