LSRD(*args, copy=True, representation_type=None, differential_type=None, **kwargs)¶
A coordinate or frame in the Dynamical Local Standard of Rest (LSRD)
This frame is defined as a velocity of U=9 km/s, V=12 km/s, and W=7 km/s in Galactic coordinates or 16.552945 km/s towards l=53.13 b=25.02. This is defined in:
Delhaye 1965, Solar Motion and Velocity Distribution of Common Stars.
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 LSRD.
