We describe the construction of a catalogue of galaxies in the optical field of the
Hubble Deep Field South. The HDF-S observations produced WFPC2 images in , and
I, the version 1 data have been made public on 23 November 1999. The effective field of
view is 4.38 arcmin2, and the 5σ limiting magnitudes (in a FWHM aperture)
are 28.87, 29.71, 30.19, 29.58 in the
and I bands, respectively. We created a
catalogue for each pass-band (I814, V606, B450, U300), using
simulations to account for incompleteness and spurious sources contamination. Along
with photometry in all bands, we determined on the I814-selected catalogue
(
) structural parameters, such as a metric apparent size, derived from the
petrosian radius, an asymmetry index, light concentration indexes and the mean surface
brightness within the petrosian radius.
