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)
      2   Interacting doubles (galaxies of comparable size)
      3   Interacting triples
      4   Interacting quartets
      5   Interacting quintets
      6   Ring galaxies (or morphologically similar objects)
      7   Galaxies with (linear) jets
      8   Galaxies with apparent companion(s)
      9   M51-types (companion at end of spiral arm)
     10   Galaxies with peculiar spiral arms
     11   Three-armed spirals and multiple-armed spirals
     12   Peculiar disks (major asymmetry or deformation)
     13   Compact (very high-surface-brightness) galaxies
     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)
     21   Stellar objects with associated nebulosity
     22   Miscellaneous (rare or distinctive objects)
     23   Close pairs (not visibly interacting)
     24   Clode triples (not visibly interacting)
     25   Planetary nebulae
Note (5):
    The Cartesian  coordinates of the  object are measured  from the lower
    left-hand (south-east) corner of the original SERC plate.

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.
