Note (1): Stars having identical catalog numbers, whether binary or not,
are distinguished by using the designations .1 and .2 in
bytes 10-11.
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 103K
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 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. Sion, NATO ASI Series, Series C, 336:
Dordrecht, Kluwer, p. 39)
6 = Liebert, Dahn and Monet (1988ApJ...332..891L 1988ApJ...332..891L)
7 = Bergeron, Ruiz and Leggett (1997ApJS..108..339B 1997ApJS..108..339B)
8 = Liebert et al., (1997, in "White Dwarfs", ed. J.Isern, M. Hernanz &
Garcia-Berro, Dordrecht: Kluwer, p. 85)
9 = Smith (1998, Ph.D Thesis, Florida Institute of Technology,
Melbourne, Fl.)
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).
