III/210         Spectroscopically Identified White Dwarfs  (McCook+, 1999)

A Catalogue of Spectroscopically Identified White Dwarfs (4th edition, V.2) McCook G.P., Sion E.M. <Astrophys. J. Suppl. Ser. 121, 1 (1999)> =1999ApJS..121....1M
ADC_Keywords: Stars, white dwarf Description: A catalog of 2249 white dwarfs which have been identified spectroscopically is presented complete through 1996 April. This compilation is the fourth edition of the Villanova Catalog of Spectroscopically Identified White Dwarfs. For each degenerate star, the following data entries with references are provided: (1) catalog coordinate designation or WD number, in order of right ascension; (2) the right ascension and declination for epoch 1950.0; (3) the spectral type based upon the new system; (4) a catalog symbol denoting binary membership; (5) a list of most names known to exist for a given star; (6) proper motion and position angle; (7) broad-band UBV Photometry, V, B-V, U-B; (8) multichannel spectrophotometry, V(MC), g-r; (9) Stroemgren narrow-band photometry y, b-y, u-b; (10) an absolute visual magnitude based upon the best available color-magnitude calibration or trigonometric parallax; (11) the observed radial velocity uncorrected for gravitational redshift or solar motion; and (12) the trigonometric parallax with mean error when available. A Notes section for unusual or peculiar stars and a coded Reference Key alphabetized by the first author's last name are presented, as well as an expanded table cross-referencing all names to catalog WD number. An introduction and full descriptions of the entries are provided in the text. File Summary:

Note (1): Stars having identical catalog numbers, whether binary or not, are distinguished by using the designations .1 and .2 in bytes 9-10 Note (2): PosFlag specifies the accuracy (and in some cases precision) to which the equatorial coordinates are given: 1: RA given in hours, minutes and seconds; Dec given in degrees, arcminutes, and tenths 2: RA originally in hours, minutes and tenths, which were converted to minutes and seconds; Dec given in degrees and whole minutes 3: RA originally in hours, minutes and tenths, which were converted to minutes and seconds; Dec given in degrees, minutes and tenths 4. RA given in hours, minutes and seconds; Dec given in degrees and whole arcminutes 5. RA originally in hours and whole minutes, seconds were entered as 00; Dec given in degrees and whole arcminutes Note (3): For DO and DOZ white dwarfs, AbsMag is a directly derivable effective temperature value. These are given in units of 103 K A ':' for uncertain AbsMag may appear also (WD 0736+053) Note (4): In cases where only an estimated proper motion is reported in the Lowell proper-motion surveys, the "pm" field is blank and a corresponding code is given there in "Epm" field. These codes are defined in Giclas et al. (1967, 1970) and are the following: 0: Stars of blue color whose motions are too small to definitely verify on all plates. 1: pm ≤ 0.1 arcsec/yr 2: 0.1 ≤ pm < 0.2 arcsec/yr 3: 0.2 ≤ pm < 0.26 arcsec/yr Note (5): The codes to indicate the method of calculation of the absolute magnitude are: 1 = trigonometric parallax (>0.1arcsec) 2 = multichannel spectrophotometric colors 3 = uvby (Stroemgren) colors 4 = UBV photometry 5 = Teff value from Wesemael, Green and Liebert (1993PASP..105..761W), Werner and Heber (1992, in "The Atmospheres of Early-Type stars", ed. U. Heber & S. Jeffrey, Springer, p. 273) or Napiwotzki and Schonberner (1991, in "White Dwarfs", ed. G. Vauclair and E.M.
