VizieR Online Data Catalog: Fundamental parameters of Tycho-2 & TGAS stars (Stevens+, 2017)

We begin with the Tycho-2 catalog (I/259) as our base sample, providing ~2 million stars with B_T and V_T magnitudes as well as astrometry that the Gaia team has used to provide parallaxes in its first data release (DR1, Cat. I/337). We queried VizieR (Ochsenbein et al. 2000A&AS..143...23O) for photometry in the U, B, and V bands from Mermilliod (2006, Cat. II/168); in Stromgren b and y from Paunzen (2015, J/A+A/580/A23); in B_T and V_T from the Tycho-2 catalog (Hog et al. 2000, I/259); and in J, H, and K_S from the Two-Micron All Sky Survey (2MASS; Cutri et al. 2003, Cat. II/246; Skrutskie et al. 2006, Cat. VII/233). We also queried VizieR for spectroscopically determined effective temperatures T_eff and metallicities to use in our analysis. We began by searching for matches from the first LAMOST data release catalog (Luo et al. 2015, Cat. V/146), choosing the source with the closest match within 0.1'. If no LAMOST match was found, we then searched the fourth RAVE data release catalog (Kordopatis et al. 2013, Cat. III/272). If no RAVE match was found, we then searched the Apache Point Observatory Galactic Evolution Experiment (APOGEE) 13th data release (Blanton et al. 2017AJ....154...28B) from the Sloan Digital Sky Survey (SDSS Collaboration et al. 2016, arXiv:1608.02013). We adopt the parallax measurements from Gaia (Gaia Collaboration 2016, Cat. I/337). A total of 424489 stars in our sample have parallaxes in the Tycho-Gaia Astrometric Solution (TGAS) sample (Cat. I/337).
