note
                    about the KTG
                      Catalogue. 
                    It is Part I of isolated triplets of galaxies
                    researched by a group of Russian astronomers in a
                    paper published in Astrofizicheskie Issledovaniia,
                    vol. 11 in 1979. This list contains 84 isolated
                    triples of northern-hemisphere galaxies with
                    apparent magnitudes of the components m < 15.7
                    mag.  There
                    is a similar list for the southern hemisphere, KTS Abstract of
                      the original paper A
                    list of 84 northern isolated galaxy triplets with
                    component apparent magnitudes no fainter than 15.7
                    is compiled on the basis of a complete examination
                    of Palomar Sky Survey prints. Equatorial
                    coordinates, photographic apparent magnitudes,
                    angular diameters, angular separations,
                    morphological types, radial velocities, and other
                    characteristics of the triplet members are provided,
                    along with finding charts. Three main types of
                    triplet configuration are distinguished: double,
                    line, and triangle. It is shown that triple systems
                    constitute 0.8% of northern galaxies brighter than
                    15.7 mag, that 64% of the triplets are 'completely
                    isolated', and that 24% of the triplet members are
                    elliptical and lenticular galaxies, while 76% are
                    spirals and irregulars. Note: These are fairly raw notes out of my notebook. All object parameters in parenthesis are
                listed in RA, Dec, size and listed magnitude without
                commas. | |

                This trio was observed while it was fairly low
                over the SE horizon and the skies there wasn’t that
                great, probably about mag 5.
