Detailed Description

The base abstract class for sky objects used in Stellarium like Stars, Planets, Constellations etc...

Normally you should use StelObjectP instead of StelObject* which have by default the same behaviour, but which can be added reference counting if needed.

Member Enumeration Documentation

used as named bitfield flags as specifiers to filter results of getInfoString.

The precise definition of these should be documented in the getInfoString documentation for the derived classes for all specifiers which are defined in that derivative. Use InfoStringGroup instead.

Enumerator
Name 

An object's name.

CatalogNumber 

Catalog numbers.

Magnitude 

Magnitude related data.

RaDecJ2000 

The equatorial position (J2000 ref)

RaDecOfDate 

The equatorial position (of date)

AltAzi 

The position (Altitude/Azimuth)

Distance 

Info about an object's distance.

Size 

Info about an object's size.

Extra1 

Derived class-specific extra fields.

Extra2 

Derived class-specific extra fields.

Extra3 

Derived class-specific extra fields.

PlainText 

Strip HTML tags from output.

HourAngle 

The hour angle + DE (of date)

AbsoluteMagnitude 

The absolute magnitude.

GalCoordJ2000 

The galactic position (J2000 ref) GZ: HEY STOP! GalCoords are DEFINED in B1950 coordinates! What we have here is a transformation matrix preconfigured to do precession J2000->B1950 and Equ.B1950->Gal. But "GalCoord for J2000" does not make sense.
