Class BuildTestPluto99

java.lang.Object
  |
  +--BuildTestPluto99

public class BuildTestPluto99

extends java.lang.Object

Contains methods used to build jephem.astro.planets.Pluto99.java.
This class is NOT part of 'jephem' package, and can be useful to developpers who want to transform BDL Pluto99 file.
See a description of its use in the page about Pluto99 of JEphem site.
BuildTestPluto99 needs to have in the current directory the file plutoxyz.dat which can be found at ftp://ftp.bdl.fr/pub/polac/solarsys/pluto.

Method Summary

static void	buildPluto99(java.lang.String strUnit) Method used to transform 'plutoxyz.dat' to a java array.
static void	calcGeoPrec() Small method which calculates the geocentric precision an error of 0.00005 u.a. represents.
static void	main(java.lang.String[] args) Dispatches the call to different methods, depending on first argument.
static void	testPositions() Method used to test first version of class Pluto99 (with phi in degrees); values taken from NOTICE.
static void	testVelocities() Method used to test the second version of class Pluto99 (with phi in radians); The refence values are obtained from Pluto99_deg.java., in the current directory

Method Detail

buildPluto99

public static void buildPluto99(java.lang.String strUnit)

Method used to transform 'plutoxyz.dat' to a java array.
Only terms 'Ampli', 'Nu' and 'Phi' are used.
It generates a file 'result.txt' which contains a java formatted array containing the terms of Pluto99.

Parameters:

strUnit - : can be "radians" or "degrees", depending on the unit you want phi to be expressed.

calcGeoPrec

public static void calcGeoPrec()

Small method which calculates the geocentric precision an error of 0.00005 u.a. represents.

main

public static void main(java.lang.String[] args)

Dispatches the call to different methods, depending on first argument.

Parameters:

args - The first argument must be one of ARG_XXX constants ; indicates which method will be called. The following arguments are passed to the called method.

testPositions

public static void testPositions()

Method used to test first version of class Pluto99 (with phi in degrees); values taken from NOTICE.

testVelocities

public static void testVelocities()

Method used to test the second version of class Pluto99 (with phi in radians);
The refence values are obtained from Pluto99_deg.java., in the current directory
