All Implemented Interfaces:

EOPHistory, Serializable, Iterable<TimeStamped>

public class EOP2000HistoryConstantOutsideInterval
extends EOP2000History

This class extends the EOP data outside of the historic definition interval. Outside of this interval the value corresponding to the closest bound will be returned.

Warning: as the UT1-TAI remains constant the (UT1-UTC) absolute value may become higher than 0.9 second depending on leap seconds (for UTC time scale) existing outside this interval.

Constructor Detail

EOP2000HistoryConstantOutsideInterval

public EOP2000HistoryConstantOutsideInterval(EOPInterpolators interpMethod)

Constructor.

Parameters:

interpMethod - EOP interpolation method

Method Detail

getStartDate

public AbsoluteDate getStartDate()

Description copied from class: AbstractEOPHistory

Get the date of the first available Earth Orientation Parameters.

Specified by:

getStartDate in interface EOPHistory

Overrides:

getStartDate in class AbstractEOPHistory

Returns:

the start date of the available data

getEndDate

public AbsoluteDate getEndDate()

Description copied from class: AbstractEOPHistory

Get the date of the last available Earth Orientation Parameters.

Specified by:

getEndDate in interface EOPHistory

Overrides:

getEndDate in class AbstractEOPHistory

Returns:

the end date of the available data

getUT1MinusTAI

public double getUT1MinusTAI(AbsoluteDate date)

Get the UT1-TAI value.

The data provided comes from the IERS files. It is smoothed data.

Specified by:

getUT1MinusTAI in interface EOPHistory

Overrides:

getUT1MinusTAI in class AbstractEOPHistory

Parameters:

date - date at which the value is desired

Returns:

UT1-TAI in seconds if date is within history interval bounds. If date is outside history interval bounds value corresponding to closest bound is returned

getUT1MinusUTC

public double getUT1MinusUTC(AbsoluteDate date)

Get the UT1-UTC value.

The data provided comes from the IERS files. It is smoothed data.

Specified by:

getUT1MinusUTC in interface EOPHistory

Overrides:

getUT1MinusUTC in class AbstractEOPHistory

Parameters:

date - date at which the value is desired

Returns:

UT1-UTC in seconds if date is within history interval bounds. If date is outside history interval bounds value corresponding to closest bound is returned. As the UT1-TAI remains constant the (UT1-UTC) absolute value may become higher than 0.9 second depending on leap seconds (for UTC time scale) existing outside this interval.

getLOD

public double getLOD(AbsoluteDate date)

Get the LoD (Length of Day) value.

The data provided comes from the IERS files. It is smoothed data.

Specified by:

getLOD in interface EOPHistory

Overrides:

getLOD in class AbstractEOPHistory

Parameters:

date - date at which the value is desired

Returns:

LoD in seconds if date is within history interval bounds. If date is outside history interval bounds value corresponding to closest bound is returned

getPoleCorrection

public PoleCorrection getPoleCorrection(AbsoluteDate date)
                                 throws TimeStampedCacheException

Get the pole IERS Reference Pole correction.

The data provided comes from the IERS files. It is smoothed data.

Specified by:

getPoleCorrection in interface EOPHistory

Overrides:

getPoleCorrection in class AbstractEOPHistory

Parameters:

date - date at which the correction is desired

Returns:

pole correction to be applied if date is within history interval bounds. If date is outside history interval bounds value corresponding to closest bound is returned

Throws:

TimeStampedCacheException - for TimeStampedCache problems

getNutationCorrection

public NutationCorrection getNutationCorrection(AbsoluteDate date)

Get the correction to the nutation parameters.

The data provided comes from the IERS files. It is smoothed data.

Specified by:

getNutationCorrection in interface EOPHistory

Overrides:

getNutationCorrection in class AbstractEOPHistory

Parameters:

date - date at which the correction is desired

Returns:

nutation correction to be applied if date is within history interval bounds. If date is outside history interval bounds value corresponding to closest bound is returned
