Class ExtendedSolarActivityWrapper

java.lang.Object
  org.orekit.forces.atmospheres.solarActivity.ExtendedSolarActivityWrapper

All Implemented Interfaces:

SolarActivityDataProvider

public class ExtendedSolarActivityWrapper
extends Object
implements SolarActivityDataProvider

This class is a solar activity data provider fed with:

• a user-defined SolarActivityDataProvider
• A averaged duration d

It is built with the following convention:

• It returns solar activity from user-provided solar activity data provider if date is within timespan of the user-provided solar activity data provider.
• It returns an average of first available solar data over user-defined period d if date is before lower boundary of the user-provided solar activity data provider.
• It returns an average of last available solar data over user-defined period d if date is after upper boundary of the user-provided solar activity data provider.

Constructor Detail

ExtendedSolarActivityWrapper

public ExtendedSolarActivityWrapper(SolarActivityDataProvider innerProvider,
                                    double duration)

Constructor.

Parameters:

innerProvider - underlying solar activity provider

duration - mean duration (s) for extension computation. If this duration is larger than available data timespan, d will be equal to timespan length
