Beginning of ReadMe : J/A+A/448/579 Sample of confirmed WDs in GSC-II survey (Carollo+, 2006) ================================================================================ The GSC-II-based survey of ancient cool white dwarfs. I. The sample of spectroscopically confirmed WDs. Carollo D., Bucciarelli B., Hodgkin S.T., Lattanzi M.G., McLean B., Morbidelli R., Smart R.L., Spagna A., Terranegra L. <Astron. Astrophys. 448, 579 (2006)> =2006A&A...448..579C ================================================================================ ADC_Keywords: Surveys ; Stars, white dwarf ; Proper motions ; Photometry Keywords: stars: white dwarfs - astrometry - techniques: spectroscopic - surveys Abstract: The GSC-II white dwarf survey was designed to identify faint and high proper motion objects, which we used to define a new and independent sample of cool white dwarfs. With this survey we aim to derive new constraints on the halo white dwarf space density. Also, these data can provide information on the age of thick disk and halo through the analysis of the luminosity function. On the basis of astrometric and photometric parameters, we selected candidates with mu>0.28mas/yr and RF>16 in an area of 1150 square degrees. Then, we separated white dwarfs from late type dwarfs and subdwarfs by means of the reduced proper motion diagram. Finally, spectroscopic follow-up observations were carried out to confirm the white dwarf nature of the selected candidates. We found 41 white dwarfs of which 24 are new discoveries. Here we present the full sample and for each object provide positions, absolute proper motions, photometry, and spectroscopy. Description: The GSC-II white dwarf survey catalogue contains astrometry photometry and classification for 41 cool white dwarfs. For each object equatorial coordinates, absolute proper motions, photographic photometry (BJ, RF), SDSS and 2MASS photometry, spectroscopic classification, and cross-match with Luyten's catalogue (LHS, NLTT) are given. Position accuracy is in the range of 0.2"-0.3" while proper motions have a typical total error between 2 and 6mas/yr. Magnitudes are between 15.1<RF<19.7 and colors in the range -0.1<BJ-RF<1.9. Proper motions are in the range (0.2-1.1)mas/yr.
