Bases: astropy.coordinates.BaseCoordinateFrame
A coordinate or frame in the ICRS system.
If you’re looking for “J2000” coordinates, and aren’t sure if you want to use this or FK5, you probably want to use ICRS. It’s more well-defined as a catalog coordinate and is an inertial system, and is very close (within tens of milliarcseconds) to J2000 equatorial.
For more background on the ICRS and related coordinate transformations, see the references provided in the See Also section of the documentation.
