Description: (Abstract in the documentation file "docu.txt")
The "Southern Galaxy Catalogue" provides a finding list of galaxies
larger than about 1.5 to 2 arc minutes, south of declination -17
degrees. It includes, as far as possible, precise positions,
morphological types, luminosity classifications, and diameters. It is
essentially complete for logD>1.52.
Notes:
* Detail, see "docu.txt" (document) file.
* The remark flag 'r' in column 68 of the original "catalog" file has been
shifted to column 74 in accordance with the other case of full EU name.
