The associated catalogs from Kamdar+ (2019) on co-moving pairs in Gaia DR2 + LAMOST DR4 are here and here. The two separate files have identical columns and list properties for the individual stars in the pair.

The columns in these files are:

  1. gidp: Gaia DR2 ID
  2. xp: Galactocentric X [kpc]
  3. yp: Galactocentric Y [kpc]
  4. zp: Galactocentric Z [kpc]
  5. vxp: Galactocentric VX [km/s]
  6. vyp: Galactocentric VY [km/s]
  7. vzp: Galactocentric VZ [km/s]
  8. rap: RA [deg]
  9. decp: Declination [deg]
  10. parallaxp: Parallax [mas]
  11. pmrap: Proper Motion (RA) [mas/yr]
