a: SIMBAD lists as variable or suspected variable, but Hipparcos
a  finds scatter in Hp<=0.015mag. The typical scatter for the other
a  standard stars was 0.005 mag in Hp (Hipparcos magnitude), with
a  none greater than 0.01mag.
b: Spectroscopic binary.
c: From standard list of Garcia (1989, Cat. <III/149>) and originally
c  in Johnson & Morgan (1953ApJ...117..313J), but not listed in
c  either Keenan & Yorka (1988BICDS..35...37K) or
c  Keenan & McNeil (1989, Cat. <III/150>).
d: HR 5409 is a resolved binary (separation of 5") listed by SIMBAD
d  as a variable star, but Hipparcos found the scatter in the Hp
d  band to be only 0.015mag.
e: HR 5072 is the planet host 70 Vir. Keenan & McNeil (1989,
e  Cat. <III/150>) call it G4 V, however it is G5 V in virtually
e  every other reference (e.g., Gray, Graham & Hoyt,
e  2001AJ....121.2159G). We retain Keenan's classification
f: Hipparcos "G" binary.
g: CCDM J12165-5009AB. Unresolved binary ({rho}=0.2")
h: The Michigan Spectral Survey (Houk, 1978, <III/51>) classifies
h  this star as K0/2(V)+(G) (quality = 3). We found it to be much
h  earlier (G1.5) and note that the published b-y and B-V colors
h  support an early G classification.
i: Star "E" of Soderblom, King, & Henry (1998AJ....116..396S)
i  high-resolution survey of active southern stars. It is the most
i  Li-rich of the very active stars in the Soderblom sample. We did
i  not resolve this tight, equal-brightness binary
i  ({rho}=0.2"; CCDM J13431-6908AB).
j: CCDM J15304-3218AB. Both stars were on the slit ({rho}=1.5")
k: [KWS97] Lupus 1 26 = CCDM J15450-3412AB. Binary is resolved
k  ({rho}=3.4") but both were on-slit.
l: [KWS97] TTS 79 = CCDM J15450-3412AB. Unresolved binary ({rho}=0.2")
m: Star #10 = HIP 59721 is a common proper motion pair ({rho}=24")
m  with HD 106444 = HIP 59716 (F5V, {pi}=9.92+/-2.53)
n: Star #19 = Einstein Slew Survey source 1ES 1233-63.4

p: Star #27 = 2E 1255.1-7012 = EUVE J1258-70.4
q: Star #34 = PDS 66 = Hen 3-892 = IRAS 13185-6922. This is the
q  lone classical T Tauri star identified in this survey.
q  [O I] {lambda}6300 is seen in emission (EW = 0.2{AA}).
r: Star #46 = CCDM J1437-4145AB. Unresolved binary ({rho} =0.4")
