        * *.obs.* are convolved observable coordinates and error bars. The 11 columns are: apparent V magnitude, RA, dec, parallax, parallax error, proper motion in RA, PM_{RA} error, PM in dec, PM_{dec} error, RV, RV error.
   * [[http://user.astro.columbia.edu/~robyn/SphericalIsochrone.GaiaOnly/SphericalIsochrone.GaiaOnly.20streams.tgz|SphericalIsochrone.GaiaOnly.20streams.tgz]] --- subset of 20 streams convolved with Gaia errors, same naming convention/columns as above
