Notes. ^(a) Heliocentric radial velocity. ^(b) Equivalent widths of interstellar NaD lines. A question mark means that the line is so badly blended by a stellar or telluric line that it could not be measured. ^(c) Single-lined spectroscopic binaries according to the SIMBAD database are designated with SB1.
