Detailed Description

A Quasar object represents one Quasar on the sky.

Details about the Quasars are passed using a QVariant which contains a map of data from the json file.

Definition at line 41 of file Quasar.hpp.

Constructor & Destructor Documentation

Quasar::Quasar ( const QVariantMap &  map)
Parameters
idThe official designation for a quasar, e.g. "RXS J00066+4342"

Member Function Documentation

virtual double Quasar::getAngularSize ( const StelCore core) const
virtual

Return the angular radius of a circle containing the object as seen from the observer with the circle center assumed to be at getJ2000EquatorialPos().

Returns
radius in degree. This value is the apparent angular size of the object, and is independent of the current FOV.

Implements StelObject.

virtual QString Quasar::getEnglishName ( void  ) const
inlinevirtual

Return object's name in english.

Implements StelObject.

Definition at line 94 of file Quasar.hpp.

virtual QString Quasar::getID ( void  ) const
inlinevirtual

Returns a unique identifier for this object.

The ID should be unique for all objects of the same type, but may freely conflict with IDs of other types, so getType() must also be tested.

With this it should be possible to at least identify the same object in a different instance of Stellarium running the same version, but it would even be better if the ID provides some degree of forward-compatibility. For some object types (e.g. planets) this may simply return getEnglishName(), but better candidates may be official designations or at least (stable) internal IDs.

An object may have multiple IDs (different catalog numbers, etc). StelObjectMgr::searchByID() should search through all ID variants, but this method only returns one of them.

Implements StelObject.

Definition at line 66 of file Quasar.hpp.

virtual Vec3f Quasar::getInfoColor ( void  ) const
virtual

Get a color used to display info about the object.

Reimplemented from StelObject.

virtual QVariantMap Quasar::getInfoMap ( const StelCore core) const
virtual

Return a map like StelObject::getInfoMap(), but with a few extra tags also available in getMap().

  • amag
  • bV
  • redshift

Reimplemented from StelObject.

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

Get an HTML string to describe the object.

Parameters
coreA pointer to the core a set of flags with information types to include.

Implements StelObject.

virtual Vec3d Quasar::getJ2000EquatorialPos ( const StelCore core) const
inlinevirtual

Get observer-centered equatorial coordinates at equinox J2000.

Implements StelObject.

Definition at line 84 of file Quasar.hpp.

QVariantMap Quasar::getMap ( void  ) const

Get a QVariantMap which describes the Quasar.

Could be used to create a duplicate.

  • designation
  • Vmag
  • Amag
  • bV
  • RA
  • DE
  • z
virtual QString Quasar::getNameI18n ( void  ) const
inlinevirtual

Return translated object's name.

Implements StelObject.

Definition at line 90 of file Quasar.hpp.

virtual float Quasar::getSelectPriority ( const StelCore ) const
virtual

Return a priority value which is used to discriminate objects by priority As for magnitudes, the lower is the higher priority.

Reimplemented from StelObject.

virtual QString Quasar::getType ( void  ) const
inlinevirtual

Return object's type. It should be the name of the class.

Implements StelObject.

Definition at line 61 of file Quasar.hpp.

virtual float Quasar::getVMagnitude ( const StelCore core) const
virtual

Return object's apparent V magnitude as seen from observer, without including extinction.

Reimplemented from StelObject.
