Description:
The catalog contains all bibliographical information pertaining to
rotation curves of external galaxies that have appeared in the
astronomical literature up to 1981 December. Information about 271
galaxies is given from 332 papers. The catalog includes galaxy names,
morphological types, positions, radial velocities, approximate extent
of the rotation curves from the centers of the galaxies, and
references.

Historical Notes:
* The magnetic tape was sent in July 1985 by G.G.C Palumbo to
C. Jaschek, Director of CDS (Centre de Donnees de Strasbourg, France)
* From ADC: The catalogue was received by the Astronomical Data Center,
NASA Goddard Space Flight Center, from the Centre de Donnees de
Strasbourg (CDS), in February 1986.
The original tape contained two text files formatted in the same
manner as in the published catalog. An editor was used to compress the
data file from 76- to 56-byte records by removing extra blank columns,
as well as to make minor format changes in some name and radial
velocity for uniformity.
A FORTRAN program was run that checked the validity of each field
according to its data type and value.
As a result of running this program, it was determined that
approximately 5% of the right ascensions listed were obviously in
error (for example, the value given for NGC 1087 was 2 hours,
43 minutes, 86 seconds). This prompted a closer examination of all
the coordinates. It was discovered that at least 15% of the right
ascensions given in the catalog suffered from the same error - a right
ascension of, for example, 38.3 minutes being listed as 38 minutes, 3
seconds. Several negative signs in the declination field were also
missing. At that point it was decided to replace all the coordinates
by equinox 1950.0 coordinates from other catalogs. The RC2 (Catalog
VII/112) and UGC (Catalog VII/26) catalogs were used whenever
possible. Coordinates for objects not listed in either of these were
obtained from the source catalogs.
During this process, two entries for VV 147 were encountered with
conflicting coordinates. By comparing coordinates in the source
catalog, it was determined that the first object listed was actually
VV 141. The name field of that entry was changed to reflect this.
An editor was also used to change the references file to upper and
lower case, to add blanks, and to expand abbreviations. Several minor
typographical errors were also corrected.
* From CDS (December 1995): The description was standardized. A
further error in the right ascension of NGC 4753 was corrected,
and the references have been reformatted.
