Abstract:
Surface photometry was made for 137 galaxies on a UK Schmidt plate whose
center is located at the center of the Hydra I (A1060) cluster of galaxies.
For 133 of 137 galaxies the photometric parameters such as total magnitude,
equivalent radius, concentration indices, and mean surface brightness were
obtained. The total magnitudes were compared with those in the literature
to check the accuracy of the present data. The estimated accuracy in the
total magnitudes is about 0.1 mag at most for majority of the galaxies.
This catalog is an updated version from the published paper.
