Descripción
We present a photometric survey of bright southern stars carried out
using the DENIS instrument equipped with attenuating filters. The
observations were carried out not using the survey mode of DENIS, but
with individual target pointings. This project was stimulated by the
need to obtain near-infrared photometry of stars to be used in early
commissioning observations of the ESO Very Large Telescope
Interferometer, and in particular to establish a network of bright
calibrator sources. We stress that near-infrared photometry is
peculiarly lacking for many bright stars. These stars are saturated in
2MASS as well as in regular DENIS observations. The only other
observations available for bright infrared stars are those of the Two
Micron Sky Survey () dating from over thirty years ago.
These were restricted to declinations above -30° and thus cover only
about half of the sky accessible from the VLTI site. We note that the
final 2MASS data release includes photometry of bright stars, obtained
by means of point-spread function fitting. However, this method only
achieves about 30 percent accuracy, which is not sufficient for most
applications. In this work, we present photometry for over 600 stars,
each with at least one and up to eight measurements, in the J and K
filters. Typical accuracy is at the level of 0.05mag and 0.04mag in the
J and Ks bands, respectively.
