Detailed Description

A subclass of KSPlanetBase that implements comets.

The orbital elements are stored as private member variables, and it provides methods to compute the ecliptic coordinates for any time from the orbital elements.

The orbital elements are:

• JD Epoch of element values
• q perihelion distance (AU)
• e eccentricity of orbit
• i inclination angle (with respect to J2000.0 ecliptic plane)
• w argument of perihelion (w.r.t. J2000.0 ecliptic plane)
• N longitude of ascending node (J2000.0 ecliptic)
• Tp time of perihelion passage (YYYYMMDD.DDD)

Member Function Documentation

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

Calculate the geocentric RA, Dec coordinates of the Comet.

Note:

reimplemented from KSPlanetBase

Parameters:

	num	time-dependent values for the desired date
	Earth	planet Earth (needed to calculate geocentric coords)

Returns:

true if position was successfully calculated.

Implements KSPlanetBase.

[virtual]

Unused virtual function inherited from KSPlanetBase, so it's simply empty here.
