VII/77     Isolated Pairs of Galaxies in Northern Hemisphere (Karachentsev 1972)

Catalogue of Isolated Pairs of Galaxies in the Northern Hemisphere Karachentsev I.D. <Publ. of the Special Astrophy. Observatory of USSR AS, No. 7 (1972)> =1972SoSAO...7....1K
ADC_Keywords: Galaxy catalogs ; Morphology Description: The catalog is a compilation of observational data for 603 isolated pairs of galaxies with component magnitudes brighter than 15.7 and north of declination -3 degrees. The catalog includes pair numbers and component letters, coordinates, apparent magnitudes, radial velocities, major axes and eccentricities, Hubble classifications, spectral types, and distances between components.

Note on ID: Running number of the pairs in this catalog; named K72 in SIMBAD data-base, KPG in NED. Note on m_ID: Indicates to which component of the pair the data refer. This is always either A or B. Note on RV: Radial velocity corrected for the Sun's motion Note on r_RV: Sources of radial velocities are: =1= Karachentsev I.D., 1980ApJS...44..137K Karachentsev I.D., 1981, Sov. Astron.

Remarks and Modifications: The Catalogue of Isolated Pairs of Galaxies in the Northern Hemisphere was received by the Astronomical Data Center (ADC), NASA Goddard Space Flight Center, from the Centre de Donnes Astronomiques, Strasbourg (CDS), in February 1986. The original tape contained only the single text file. (Although Karachentsev et al. (1985) refers to a second file of documentation, this was apparently not included in the data received from the CDS.) An editor was used to compress the data file from 70 to 59-byte records by removing blank columns. The data required no further editing. A FORTRAN program was run that checked the validity of each field according to its data type and value. Addendum (27-Apr-1987): In a private communication dated 18 December 1986 and received by the Astronomical Data Center 23 April 1987, V. Lebedev notes that the Catalogue of Isolated Pairs of Galaxies in the Northern Hemisphere lists several galaxy-star pairs. While these objects have the same coordinates and radial velocities, there is no information for them regarding the type of the galaxy or the type of its linear spectrum.
