Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Description:
        This  "Catalogue of Southern Peculiar Galaxies and Associations"  is a
        complete and  detailed catalogue of all  the most interesting galaxies
        and  most striking apparent  associations of galaxies  in the Southern
        sky.
        The printed catalogue is made of two volumes: Volume I which lists the
        Peculiar  Galaxies,  and  Volume  II  which  contains  photographs  of
        galaxies which  are representative of the  various Categories  used in
        the Classification scheme presented in Volume I.

    Note (1):
        Note that the AM designation  is  based  on  the  1950  position  with
        "format"  HHMM+DDM, where the last 'M' digit represents truncated tens
        of arc minutes (the last digit is always between 0 and 5)
    Note (2):
        For  objects that are part of a pair, a triple or a larger association
        of objects which are  also listed  and described  in the  Catalogue as
        separate   entries,  this  number  represents  the  abbreviated  right
        ascension and declination of  the  member  immediately  preceding  the
        current object in  order of right  ascension (only the  last number of
        right ascension and the four numbers of declination are given)
    Note (3):
        S  or D, indicating that  the following number is  a measure of either
        the separation  (S) of major components,  or a characteristic diameter
        (D) of the system as a whole, respectively.
    Note (4): the following Description Codes are used:
          1   Galaxies with interacting companion(s)

         14   Galaxies with prominent or unusual dust absorption
         15   Galaxies with tails, loops of material or debris
         16   Irregular or disturbed, (apparently isolated) galaxies
         17   Chains (four or more galaxies aligned)
         18   Groups (four or more galaxies not aligned)
         19   Clusters (only very conspicuous, rich systems)
         20   Dwarf galaxies (low surface brightness)

    Historical Notes:
        The machine file of the Arp & Madore Atlas of Peculiar Galaxies (1987)
        was  kindly provided by B. Madore to H. Andernach in April 1991. A few
        formatting  errors  were  detected  by  H.  Andernach,  corrected  and
        commented to  B.Madore that time. H. Andernach  provided a copy to CDS
        in   February  1993.  Further  formatting  errors  were  detected  and
        corrected at CDS.  Two  more  errors  (diameter  of  AM  0640-505  and
        Category of AM  1934-563) were detected  by H. Andernach  in June 1996
        and corrected.
