Class FundamentalNutationArguments

java.lang.Object

org.orekit.data.FundamentalNutationArguments

public class FundamentalNutationArguments
extends Object

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)

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)

timeScales - TAI time scale

Since:

10.1
