Abstract:
We present homogeneous, standardized UBV(RI)C photometry for over 700
nearby stars selected on the basis of Hipparcos parallaxes.
Additionally, we list JHK photometry for about half of these stars, as
well as L photometry for 86 of the brightest. A number of stars with
peculiar colours or anomalous locations in various colour-magnitude
diagrams are discussed.
Description:
All UBVRI observations were made using the 0.5-m telescope and
photomultiplier-based modular photometer at the Sutherland site of the
SAAO between 2000 June and 2005 November.

Note (1): In a few cases, only UBV results are given; this is because for
some of the redder stars near the bright limit, the photometer can
measure U, B and V, but R and I are too bright for the upper limit to
the count rate.
Note (2): Hipparcos variability flags as follows:
C = not detected as variable
D = probably spurious variability, due to the presence of a close companion
M = microvariable
P = periodic variable
R = possible spurious magnitude trend, due to a revised colour index;
U = "unsolved" variable (possibly multiperiodic or irregular variable)
Note (3): Hipparcos multiplicity flags as follows:
C = solutions for multiple components
G = higher order terms required in solution
(probable long-period astrometric binary)
O = partial binary orbital element solution
V = double system with a variable component
X = model uncertainty larger than expected from errors on individual
measurements (probable short-period astrometric binary)

In case of multiple classifications this was also the order of
preference we followed. There are new (i.e. post-1994) classifications
for 648 (88 per cent) of the stars.
