Abstract:
This paper presents preliminary lists of potentially interesting
point-like sources extracted from multicolour data obtained for a 1.7
square degree region near the South Galactic Pole. The region has been
covered by the ESO Imaging Survey (EIS) in B, V and I and offers a
unique combination of area and depth. These lists, containing a total
of 330 objects nearly all brighter than I∼21.5, over 1. 27 square
degrees (after removing some bad regions), are by-products of the
process of verification and quality control of the object catalogs
being produced. Among the colour selected targets are candidate very
low mass stars/brown dwarfs (54), white-dwarfs (32), and quasars
(244). In addition, a probable fast moving asteroid was identified.
The objects presented here are natural candidates for follow-up
spectroscopic observations and illustrate the usefulness of the EIS
data for a broad range of science and for providing possible samples
for the first year of the VLT.
