FK4NoETerms

class astropy.coordinates.FK4NoETerms(*args, **kwargs)[source] [edit on github]

Bases: astropy.coordinates.BaseCoordinateFrame

A coordinate or frame in the FK4 system, but with the E-terms of aberration removed.

Parameters:

representation : BaseRepresentation or None

A representation object or None to have no data (or use the other keywords)

ra : Angle, optional, must be keyword

The RA for this object (dec must also be given and representation must be None).

dec : Angle, optional, must be keyword

The Declination for this object (ra must also be given and representation must be None).

distance : Quantity, optional, must be keyword

The Distance for this object along the line-of-sight. (representation must be None).

obstime : astropy.time.Time, optional, must be keyword

The time this frame was observed. If None, will be the same as equinox.
