public var l: Degree { get } -
A convenience accessor for the galactic latitude
Declaration
Swift
public var b: Degree { get } -
Creates a new GalacticCoordinates instance.
Declaration
Parameters
galacticLongitudeThe galactic longitude
galacticLatitudeThe galactic latitude
epochThe epoch of coordinates. Default is B1950.0
equinoxThe optional equinox, default to standard equinox J2000.0.
-
Creates a new GalacticCoordinates instance.
Declaration
Parameters
lThe galactic longitude
bThe galactic latitude
epochThe epoch of coordinates. Default is B1950.0
-
Returns the equatorial coordinates corresponding to the current galactic one. Careful: the epoch should necessarily be that of the galactic coordinates which is always B1950.0.
