Constructor & Destructor Documentation

KSSun::KSSun	(	KStarsData *	kd,
		QString	fn = "",
		double	pSize = 0
	)

Constructor.

Defines constants needed by findPosition(). Sets Ecliptic coordinates appropriate for J2000.

Parameters:

	kd	pointer to KStarsData object
	fn	filename of Sun image
	pSize	physical diameter of the Sun, in km

bool KSSun::findGeocentricPosition	(	const KSNumbers *	num,
		const KSPlanetBase *	Earth = NULL
	)			[protected, virtual]

Determine geocentric RA, Dec coordinates for the Epoch given in the argument.

Epoch current Julian Date Earth pointer to earth object

Reimplemented from KSPlanet.

bool KSSun::loadData

(

)

[virtual]

Read orbital data from disk.

Note:

reimplemented from KSPlanet

we actually read Earth's orbital data. The Sun's geocentric ecliptic coordinates are by definition exactly the opposite of the Earth's heliocentric ecliptic coordinates.
