Definition: StelObject.hpp:36
Define the StelTextureSP type.
virtual double getAngularSize(const StelCore *core) const
Return the angular radius of a circle containing the object as seen from the observer with the circle...
virtual Vec3d getJ2000EquatorialPos(const StelCore *) const
Get observer-centered equatorial coordinates at equinox J2000.

virtual QString getEnglishName(void) const
Return object&#39;s name in english.
Definition: Quasar.hpp:87
virtual QVariantMap getInfoMap(const StelCore *core) const
Return a map like StelObject::getInfoMap(), but with a few extra tags also available in getMap()...
A Quasar object represents one Quasar on the sky.
Definition: Quasar.hpp:41
virtual QString getInfoString(const StelCore *core, const InfoStringGroup &flags) const

QVariantMap getMap(void) const
Get a QVariantMap which describes the Quasar.
virtual QString getType(void) const
Return object&#39;s type. It should be the name of the class.
Definition: Quasar.hpp:59
virtual float getVMagnitude(const StelCore *core) const
Return object&#39;s apparent V magnitude as seen from observer, without including extinction.
QSharedPointer< StelTexture > StelTextureSP
