Detailed Description

Class which contains data about one Nomenclature entry from the IAU database at https://planetarynames.wr.usgs.gov/ There is a confusing variety of planetographic vs.

planetocentric coordinate systems, counting longitudes in eastern or western direction, or counting from 0...360 degrees or from -180...+180 degrees. The actual data were taken from https://planetarynames.wr.usgs.gov/GIS_Downloads and include eastward-positive planetocentric coordinates, i.a. all bodies are treated as spheres. However, according to https://planetarynames.wr.usgs.gov/TargetCoordinates on some objects at least the longitudes should be counted west-positive, a convention which we should follow closely. Note that for Mars the traditional west-positive counting has recently been inverted, and longitudes are now counted east-positive like on earth.

Member Function Documentation

◆ getAngularRadius()

double NomenclatureItem::getAngularRadius ( const StelCore * core ) const

overridevirtual

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

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

Reimplemented from StelObject.

◆ getID()

QString NomenclatureItem::getID ( void ) const

inlineoverridevirtual

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.

◆ getInfoString()

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

overridevirtual

Get an HTML string to describe the object.

Parameters

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

Implements StelObject.

◆ getObjectType()

QString NomenclatureItem::getObjectType ( void ) const

inlineoverridevirtual

Return object's type.

It should be English lowercase name of the astronomical type of the object. The purpose of this string is a distinction or further refinement over object class name retrieved with getType(): Planet objects can be planets, moons, or even the Sun. The Sun should however return "star". Nebula objects should return their actual type like "open cluster", "galaxy", "nebula", ...

Implements StelObject.

◆ getRTSTime()

Vec4d NomenclatureItem::getRTSTime	(	const StelCore *	core,
		const double	altitude = `0.`
	)		const

overridevirtual

Compute times of nearest rise, transit and set of the item's current Planet.

Parameters

core	the currently active StelCore object
altitude	(optional; default=0) altitude of the object, degrees.

Returns: Vec4d - time of rise, transit and set closest to current time; JD.

Note

The fourth element flags particular conditions:

+100. for circumpolar objects. Rise and set give lower culmination times.
-100. for objects never rising. Rise and set give transit times.
-1000. is used as "invalid" value. The result should then not be used.
