java.lang.Object

org.orekit.data.FundamentalNutationArguments

All Implemented Interfaces:

Serializable

public class FundamentalNutationArguments
extends Object
implements Serializable

Class computing the fundamental arguments for nutation and tides.

The fundamental arguments are split in two sets:

• the Delaunay arguments for Moon and Sun effects
• the planetary arguments for other planets

FundamentalNutationArguments

@DefaultDataContext
public FundamentalNutationArguments(IERSConventions conventions,
                                    TimeScale timeScale,
                                    InputStream stream,
                                    String name)

Build a model of fundamental arguments from an IERS table file.

This method uses the default data context.

Parameters:

conventions - IERS conventions to use

timeScale - time scale for GMST computation (may be null if tide parameter γ = GMST + π is not needed)

stream - stream containing the IERS table

name - name of the resource file (for error messages only)
