Motion Verified Red Stars (MoVeRS): A Catalog of Proper Motion Selected
  Low-mass Stars from WISE, SDSS, and 2MASS
  We present a photometric catalog of 8,735,004 proper motion selected low-mass
stars (KML-spectral types) within the Sloan Digital Sky Survey (SDSS)
footprint, from the combined SDSS Data Release 10 (DR10), Two-Micron All-Sky
Survey (2MASS) Point Source Catalog (PSC), and Wide-field Infrared Survey
Explorer (WISE) AllWISE catalog. Stars were selected using $r-i$, $i-z$, $r-z$,
$z-J$, and $z-W1$ colors, and SDSS, WISE, and 2MASS astrometry was combined to
compute proper motions. The resulting 3,518,150 stars were augmented with
proper motions for 5,216,854 earlier type stars from the combined SDSS and
United States Naval Observatory B1.0 catalog (USNO-B). We used SDSS+USNO-B
proper motions to determine the best criteria for selecting a clean sample of
stars. Only stars whose proper motions were greater than their $2$$\sigma$
uncertainty were included. Our Motion Verified Red Stars (MoVeRS) catalog is
available through SDSS CasJobs and VizieR.
