VII/77 Isolated Pairs of Galaxies in Northern Hemisphere (Karachentsev 1972)
================================================================================
Catalogue of Isolated Pairs of Galaxies in the Northern Hemisphere
Karachentsev I.D.

================================================================================
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 MType:
Hubble types have been chosen as follows:
'E ' : all ellipticals
'S0' : just Hubble S0 type
'Sx' , x=a,b,c: includes SBx
'Sm' : includes Irr
Note on Sp:
The codes as described in Karachentsev et al. (1985) are
'ABS' : absorption-line system
'WEK' : weak emission
'MID' : medium strength emission
'STG' : strong emission
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.
