Vec3d getEquinoxEquatorialPos (const StelCore *core) const
 Get observer-centered equatorial coordinate at the current equinox The frame has its Z axis at the planet's current rotation axis At time 2000-01-01 this frame is almost the same as J2000, but ONLY if the observer is on earth.
 
Vec3d getEquinoxEquatorialPosApparent (const StelCore *core) const
 Like getEquinoxEquatorialPos(core), but always adds refraction correction to the position.
 
Vec3d getEquinoxEquatorialPosAuto (const StelCore *core) const
 Like getEquinoxEquatorialPos(core), but adds refraction correction to the position if atmosphere is active.

virtual float getSelectPriority (const StelCore *) const
 Return a priority value which is used to discriminate objects by priority As for magnitudes, the lower is the higher priority.
 
virtual Vec3f getInfoColor () const
 Get a color used to display info about the object.
 
virtual double getCloseViewFov (const StelCore *) const
 Return the best FOV in degree to use for a close view of the object.

Detailed Description

Each Constellation consists of a list of stars identified by their abbreviation and Hipparcos catalogue numbers (taken from file: constellationship.fab), another entry in file constellation_names.eng.fab with the defining abbreviated name, nativeName, and translatable englishName (translation goes into nameI18), boundary shape from file constellations_boundaries.dat and an (optional) artistic pictorial representation. GZ NEW: The nativeName should be accessible in a GUI option, so that e.g. original names as written in a concrete book where a skyculture has been taken from can be assured even when translation is available. TODO: There should be a distinction between constellations and asterisms, which are "inofficial" figures within a sky culture. For example, Western sky culture has a "Big Dipper", "Coathanger", etc. These would be nice to see, but in different style.
