### The PPMXL Catalog

S. Röser, M. Demleitner, E. Schilbach & J. J. Vickers
PPMXL is a catalog of positions, proper motions, 2MASS- and optical photometry of 900 million stars and galaxies, aiming to be complete down to about V=20 full-sky. It is the result of a re-reduction of USNO-B1 together with 2MASS to the ICRS as represented by PPMX. This service additionally provides improved proper motions computed according to Vickers et al, 2016 (:bibcode:2016AJ....151...99V).
