Abstract:
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-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.

Note (1): Defined as .5*(W1MJDMAX-W1MJDMIN)
Note (2): see section 3.3. The values are:
000: SDSS and USNO-B proper motions are available
011: SDSS and WISE were used to calculate the proper motion
110: 2MASS and SDSS were used to calculate the proper motion
111: all 3 surveys were used in the linear filt to calculate
the proper motion
Note (3): the USE flag means:
1 = our proper motion
2 = Munn et al. (2004AJ....127.3034M 2004AJ....127.3034M, M04) proper motion
3 = both proper motions
Note (4): Values taken from Munn et al. (2004AJ....127.3034M 2004AJ....127.3034M, erratum in
2008, AJ, 136, 895).
Note (5): impossible values existing in the fits version are here removed:
* magnitudes>100; magnitude errors≥10mag were replaced by 9.999mag
* distances >1,000,000arcsec were replaced by 99.999.
