NominalFrame
(*args, **kwargs)[source]¶ Bases:
astropy.coordinates.baseframe.BaseCoordinateFrame
Nominal coordinate frame.
A Frame using a UnitSphericalRepresentation. This is basically the same as a HorizonCoordinate, but the origin is at an arbitray position in the sky. This is what astropy calls a SkyOffsetCoordinate
If the telescopes are in divergent pointing, this Frame can be used to transform to a common system.
- Attributes
- origin: SkyCoord[AltAz]
Origin of this frame as a HorizonCoordinate
- obstime: Tiem
Observation time
- location: EarthLocation
Location of the telescope
Attributes Summary
Default representation for differential data (e.g., velocity)
Default representation for position data
Mapping for frame-specific component names
