Detailed Description

Author: Bogdan Marinov

Some of the code in this class is re-used from the parent Planet class.

Definition at line 32 of file Comet.hpp.

Member Function Documentation

virtual QString Comet::getInfoString	(	const StelCore *	core,
		const InfoStringGroup &	flags
	)		const

virtual

Get a string with data about the Comet.

Comets support the following InfoStringGroup flags:

Name
Magnitude
RaDec
AltAzi
Distance
PlainText
Parameters

core the StelCore object

flags a set of InfoStringGroup items to include in the return value.

Returns
a QString containing an HMTL encoded description of the Comet.

Reimplemented from Planet.

double Comet::getSiderealPeriod ( ) const

get sidereal period for minor planet

virtual float Comet::getVMagnitude	(	const StelCore *	core,
		bool	withExtinction = `false`
	)		const

virtual

Reimplemented from Planet.

void Comet::setAbsoluteMagnitudeAndSlope	(	double	magnitude,
		double	slope
	)

sets absolute magnitude and slope parameter.

These are the parameters in the IAU's two-parameter magnitude system for comets. They are used to calculate the apparent magnitude at different distances from the Sun. They are not used in the same way as the same parameters in MinorPlanet.

void Comet::setSemiMajorAxis ( double value )

set value for semi-major axis in AU

The documentation for this class was generated from the following file:

core/modules/Comet.hpp

core	the StelCore object
flags	a set of InfoStringGroup items to include in the return value.
