Detailed Description

The Quasars plugin provides visualization of some quasars brighter than 16 visual magnitude. A catalogue of quasars compiled from "Quasars and Active Galactic Nuclei" (13th Ed.) (Veron+ 2010).

Quasars Catalog

The quasars catalog is stored on the disk in JSON format, in a file named "quasars.json". A default copy is embedded in the plug-in at compile time. A working copy is kept in the user data directory.

Configuration

The plug-ins' configuration data is stored in Stellarium's main configuration file (section [Quasars]).

Constructor & Destructor Documentation

◆ Quasar()

Quasar::Quasar ( const QVariantMap & map )

Parameters

id	The official designation for a quasar, e.g. "RXS J00066+4342"

Member Function Documentation

◆ getAngularSize()

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

virtual

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

Implements StelObject.

◆ getID()

virtual QString Quasar::getID ( void ) const

inlinevirtual

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.

◆ getInfoMap()

		const InfoStringGroup &	flags

Parameters

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