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% 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 0fm05 and 0fm04 in the J and K_s bands,
respectively.
Based on observations collected at the European Southern Observatory, La
Silla.
