    NOTES.— Units of right ascension are hours, minutes, and seconds, and the units of declination are degrees, arcminutes, and arcseconds. All coordinates have been proper motion adjusted to epoch 2000.0.
Weighted mean parallaxes and errors are calculated as follows:
   (a) Parallax is a weighted mean of the independent measurements of the references listed.
   (b) Coordinates, proper motion, and parallax are for the primary component. These quantities are not determined for the white dwarf secondary because angular separation is small.
   (c) Parallax incorporates two independent measurements (one for the primary and one for the secondary) from the CTIOPI program.
   (d) Parallax error is larger than 10% of the parallax value. Thus, 25 pc sample membership is uncertain.
   (e) Parallax incorporates two independent measurements (one for the primary and one for the secondary) from the Yale Parallax catalog.
   (f) Parallax incorporates two independent measurements (one for the primary and one for the secondary) from the Hipparcos catalog.
