LSRK
(*args, copy=True, representation_type=None, differential_type=None, **kwargs)[source]¶ Bases:
astropy.coordinates.BaseRADecFrame
A coordinate or frame in the Kinematic Local Standard of Rest (LSR).
This frame is defined as having a velocity of 20 km/s towards RA=270 Dec=30 (B1900) relative to the solar system Barycenter. This is defined in:
Gordon 1975, Methods of Experimental Physics: Volume 12: Astrophysics, Part C: Radio Observations - Section 6.1.5.
This coordinate frame is axis-aligned and co-spatial with
ICRS
, but has a velocity offset relative to the solar system barycenter to remove the peculiar motion of the sun relative to the LSRK.Attributes Summary
