--------------------------------------------------------------------------------
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 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
Note (3): For DO and DOZ white dwarfs, AbsMag is a directly derivable
effective temperature value. These are given in units of 10^5 K (0.1MK)
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
