Considering the large and growing number of observing facilities in that hemisphere, the sample aims to supply investigators with targets as homogeneous as possible to those in the Northern Catalog of Isolated Pairs of Galaxies (K72) which have been studied in a large frequency range. The paper discusses the sample degree of completeness, separation and velocity distributions. First inferences are sketched from the morphological association of pair members and from the study of the Holmberg effect. Being the primary purpose of the paper to provide a tool to investigators, an Atlas of images for the 301 best candidate pairs obtained using the Digitized Sky Survey (The Digitized Sky Survey was produced at the Space Telescope Science Institute (ST ScI) under U.S. Government grant NAG W-2166) is given. The Atlas reports for each pair member the relevant data as obtained from the current literature.</description><source format="bibcode">1995ApL....30....1R</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ApL/30.1</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/VII/77">VII/77 : Isolated pairs of galaxies catalogue (Karachentsev+ 1972)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/VII/115">VII/115 : ESO-LV catalogue (Lauberts+ 1989)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+AS/110/371">J/A+AS/110/371 : Sourthern binary galaxies.
