Returns:

fitted secular and harmonics model for pole x component

getYp

public SecularAndHarmonic getYp()

Get the fitted secular and harmonics model for pole y component.

Returns:

fitted secular and harmonics model for pole y component

getDx

public SecularAndHarmonic getDx()

Get the fitted secular and harmonics model for nutation x component.

Returns:

fitted secular and harmonics model for nutation x component

getDy

public SecularAndHarmonic getDy()

Get the fitted secular and harmonics model for nutation y component.

Returns:

fitted secular and harmonics model for nutation y component
