ADC_Keywords: Radio sources; Galaxies, radio; Galaxy catalogs
Description:
The catalog is a compilation of all published optical identifications
of extragalactic radio sources. This machine-readable version is an
updated and greatly expanded edition of the original published one;
this version contains 14585 identifications and citations to 917
papers. The data file contains most commonly used source name, number
in the 4C catalog Gower et al. (1967), and Pilkington and Scott (1965)
if applicable, right ascension and declination (equinox B1950.0),
magnitude estimate for the identification type of optical object,
identification reference, alternate name for identified object (if
known), confirmation or invalidation code and associated reference,
finding chart existence (or nonexistence), redshift, and reference for
the spectrum.
A reference file contains the references ordered by number cited in
the catalog and alphabetically by author. Completeness has been
attempted for all papers published through the end of 1982. The
present version contains fewer references than the 1974 version (which
had 935) because certain numbers were unused in the previous edition
and because certain references are no longer used in the 1983 version
and were removed. The authors have prepared this final version and
have discontinued future updates.
Introduction:
Abbreviations used in the catalog for optical and radio designations
are given in Tables I and II of Veron-Cetty and Veron (1983) but are
repeated here for convenience. The references cited are given in the
machine-readable "refs.dat" file.

Note on Name:
The most common name is used. Abbreviations and references for the radio
designations are given in Table II.
Note on 4C:
Fourth Cambridge Radio Survey Catalogue (4C)
(Pilkington and Scott 1965; Gower, Scott and Wills 1967).
Note on RAh:
The position given in the source publication is generally used without any
attempt to report the best available position; therefore, the positions
can differ for the same source as taken from various references.
Note on mag:
Magnitude estimate for the identification of the source as given in the
reference. Data are inhomogeneous and generally only rough estimates;
hence, caution is advised in their use. Magnitudes are reported to
varying precision.
Note on Nature:
Letter code indicating the nature of the proposed identification. The codes
are defined below. When this field is blank, a finding chart has been
published, but no identification proposed.
Codes for Nature of the Proposed Identification
------------------------------------------------------------------------
Code Type of Object
------------------------------------------------------------------------
B Appears only for reference 319: should be interpreted as Q.
EF Empty field.
G Galaxy. The type has not been retained, even if suggested in the
reference.
H2 H II region.
OF Obscured field
Q Quasi-stellar object. Includes all related suggested
identifications, such as quasars, stellar object, neutral
object,....
Note on Conf:
* : subsequent spectrum showed that proposed identification is a star.
Q : subsequent spectrum showed that proposed identification is really a QSO
(quasar).
W : identification was discarded on the basis of a better radio or optical
position.
OK: identification was confirmed by means of accurate radio and optical
positions; or, in the case of a quasar, by measuring its UBV color
photoelectrically.
EF: proposed identification was discarded and the field shown to be empty,
or the preceding classification as an empty field was confirmed.
OF: proposed identification was discarded and the field shown to be obscured.
Note on FCnum:
If several finding charts have been published for the same source, and if
these identifications are not confirmed, a running number for each proposed
identification is given; if two records have the same number in this field,
then the two proposed identifications are identical.
Note on Added:
blank if in original published catalog
1, 2,... if added in 1974, 1975, ...
Note on n_z:
OK indicates that the spectrum is continuous. Other indications
(e.g. *?, *, Q?) can appear here.
Note on r_z:
If this field is not blank when the redshift field (bytes 69-73) is,
then the spectrum is inconclusive.
Note on n_Nature:
An asterisk (*) is present when bytes 46-47 contain "EF" and there is no
published finding chart.
