VizieR Online Data Catalog: NOFS astrometric measurements for distant WDs (Leggett+, 2018)
Abstract
Table 1 lists 216 new US Naval Observatory Flagstaff Station (NOFS) astrometric measurements of 214 stars obtained between 1989 and 2017. Although the stars in our sample are near the faint limit of DR2 and predominantly have high proper motion, 90% have Gaia DR2 (I/345) trigonometric parallaxes. See Section 2.
The entire sample was matched to the optical photometric catalogs provided by the Sloan Digital Sky Survey (SDSS) Data Release 14 and the Pan-STARRS1 Data Release 1 (II/349). The sample was also matched to the near-infrared photometric catalogs provided by the Two Micron Sky Survey (2MASS, II/246), the Tenth Data Release of the UKIRT Infrared Deep Sky Survey (UKIDSS), the UKIRT Hemisphere Survey (UHS) J-Band Data Release, and the Visible and Infrared Survey Telescope for Astronomy (VISTA) public survey. Mid-infrared photometry was also obtained for the sample from the Wide-field Infrared Survey Explorer (WISE) ALLWISE catalog (II/328). Spitzer Space Telescope Infrared Array Camera (IRAC) photometry was also included for some stars. See Section 3. We obtained spectra of seven white dwarfs (WDs), as well as the red dwarf companion to one of the WDs. Spectra covering 490-820nm were obtained at the Gemini North and South Observatories using the GMOS instruments. The data were obtained using Gemini's Fast Turnaround program, via programs GN-2018A-FT-209 and GS-2018A-FT-206. See Section 4. (22 data files).- Publication:
