Constructor & Destructor Documentation

EECFI::StarData::StarData ( )

Class constructor (empty constructor).

Class constructor with parameters.

Parameters:

	ra	RA or galactic longitude (radians: 0, 2PI).
	dec	Dec or galactic latitude (radians: -PI/2, PI/2).
	muRa	Proper motion in RA (rad/century).
	muDec	Proper motion in Dec (rad/century).
	radVel	Radial velocity (AU/century).
	par	Parallax (radians: 0, 2PI).
	cs	Reference frame where the coordinates are refered to.

References parallax.

EECFI::StarData::~StarData ( ) [inline]

Class destructor.

StarData EECFI::StarData::changeCatalog	(	const ModelId &	modelId,
		Time &	time,
		long	newCatalog
	)			throw (CfiError)

Get the star parameters in a different catalog.

Only the RA and Dec. are computed.

Parameters:

	modelId	Model id.
	time	Time of the input star.
	newCatalog	New catalogue where the new parameters are computed.

Coord EECFI::StarData::getCart	(	const ModelId &	modelId,
		long	deriv
	)			throw (CfiError)

Get cartesian coordinates in the requested CS.

Only the position and velocity vector are computed (not the accelearation).

Class destructor.

Parameters:

	modelId	Model Id.
	deriv	flag to indicate if derivatives have to be computed (XLCFI_NO_DER, XLCFI_DER_1ST).

Get star Ra and Dec in ToD for a given time.

The object StarData values are used as a reference and it it should be given in FK5 catalog (BM2000 CS).

Parameters:

	modelId	Model id.
	time	Time for which the values are requested.
	newRa	[OUTPUT] RA of the star at time.
	newDec	[OUTPUT] Declination of the star at time.
