Note (2): The positions have quite various precisions; generally speaking most of the older stars have 1950 coordinates accurate to the arcmin from the references, while newer WDs have 2000 coordinates in the reference which were precessed back to 1950 and rounded to a 0.1arcmin accuracy. No correction has been made for proper motion. Note (3): For DO and DOZ white dwarfs, AbsMag is a directly derivable effective temperature value. These are given in units of 10^3^K A ':' for uncertain AbsMag may appear also (WD 0736+053); the 'B' indicates an absolute B magnitude. 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.

Note (6): modifications since the publication: N=New, A=Additional, C=Corrected, U=Updated Lowercase letters indicate components in the case of degenerate systems (1824+040). Note (7): * = Some recently published new white dwarfs were assigned a name based on J2000 position. Such names were transformed into B1950-based WD names by applying the appropriate precession. F = Finding Chart (T.R.Marsh) available on the online catalog: http://www.astronomy.villanova.edu/WDCatalog Note (8): The apparent velocity is the sum of the radial velocity (Doppler redshift) and the gravitational redshift, which have comparable values (see Falcon+, 2010, J/ApJ/712/585). -------------------------------------------------------------------------------- Byte-by-byte Description of file: names.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 14 A14 --- Name Common name of the object 15- 16 A2 --- --- [WD] Prefix of catalog 17- 26 A10 --- WD White Dwarf (WD) number -------------------------------------------------------------------------------- Byte-by-byte Description of file: notes.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 2- 3 A2 --- --- [WD] Prefix of catalog 4- 13 A10 --- WD White Dwarf (WD) number 16-255 A240 --- Notes Text of note for this star -------------------------------------------------------------------------------- Byte-by-byte Description of file: refs.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 2 A2 --- RefCode Reference code 4- 22 A19 --- BibCode CDS/ADS/NED BibCode 24-228 A205 --- Text Text of reference -------------------------------------------------------------------------------- History: * 13-Oct-2016: Current version (Apr 2014) downloaded from: ftp://astro5.ast.villanova.edu/mccook/Current Web Version of WD Catalog/ (Supersedes Cat.
