Member Function Documentation

◆ getAngularSize()

virtual double Nebula::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.

◆ getDSODesignation()

QString Nebula::getDSODesignation ( ) const

Returns: a designation

◆ getID()

virtual QString Nebula::getID ( ) 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()

virtual QVariantMap Nebula::getInfoMap ( const StelCore * core ) const

virtual

bmag (photometric B magnitude. 99 if unknown)
morpho (longish description; translated!)
surface-brightness A few entries are optional
bV (B-V index)
redshift

Reimplemented from StelObject.

◆ getInfoString()

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

virtual

Name
CatalogNumber
Magnitude
RaDec
AltAzi
Distance
Size
Extra (contains the Nebula type, which might be "Galaxy", "Cluster" or similar)
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 Nebula.

Implements StelObject.

◆ getMorphologicalTypeString()

QString Nebula::getMorphologicalTypeString ( ) const

Returns: the nebula morphological type string.

◆ getRegion()

virtual SphericalRegionP Nebula::getRegion ( ) const

inlinevirtual

Return the spatial region of the object.

Reimplemented from StelObject.

◆ getSurfaceArea()

float Nebula::getSurfaceArea ( void ) const

Returns: surface area in square degrees.

◆ getTypeString()

QString Nebula::getTypeString ( ) const

Returns: the nebula type code.
