Luyten Half-second Catalog

(1979 catalog of 4000 stars with high proper motion)

The Luyten Half-second Catalog (LHS) is a catalog of about 4000 stars with a proper motion greater than half a second per year. Willem Jacob Luyten last published it in 1979.

The Revised Luyten Half-second Catalog is a 2002 catalog of the same set of stars, updating and correcting the data, such as including J2000 coordinates.

The LHS is a successor to Luyten's 1955 Luyten Five Tenths Catalog, but the numbers do not correspond.
