Description:
We present a catalogue of galaxies in the HDF-S, created using the
public version 1 images of the WFPC2 data. We created a catalogue with
4 pass-band (I(814), V(606), B(450), U(300). In V(606),
B(450), U(300) and I(814), for each galaxy the catalogue gives
photometric parameters. For the I(814), we estimated also the colours
and for I(814)<26, the petrosian radius, the mean surface brightness
within the petrosian radius, light concentration indexes, that is
C_eta_ and C_abr_, and the asymmetry index as computed by Abraham
software.
