It was created using an automatic galaxy recognition program based on a discriminating analysis, the efficiency of which is estimated to be better than 99%. The nominal accuracy for galaxy coordinates calculated with the Guide Star Catalog is about 6 arcseconds. The cross-identification with galaxies available in the Lyon-Meudon Extragalactic DAtabase (LEDA) allows a calibration of the I-band photometry with the sample of Mathewson et al. (1992, ApJS, 81, 413) and Mathewson and Ford (1996, ApJS, 107, 97). Thus, the catalog contains total I-band magnitude, isophotal diameter, axis ratio, position angle and a rough estimate of the morphological type code for 20620 galaxies. The internal completeness of this catalog reaches a limiting I-band magnitude of 14.5, with a photometric accuracy of 0.18 mag. 25% of the Southern sky has been processed in this study. This database was created by the HEASARC in July 1999 based on a machine-readable version that was obtained form the CDS Data Center.
