Abstract:
The revised sample of 373 extragalactic radio sources brighter than
0.2 Jy at 1.4GHz is presented. These sources, selected from the
finding Green Bank surveys, were mapped at 1465 MHz using the VLA at
different configurations. The biases introduced into the original
GB (Maslowski, 1972AcA....22..227M) and
GB2 (Machalski, 1978AcA....28..367M) catalogues by confusion as well
as partial resolution by the VLA at its A-configuration, are
eliminated. In effect, a number of sources have been excluded, and a
few other are included into the revised sample. Now the sample is
about 99, 97 and 95 per cent complete for sources with S_1.4_>=0.55Jy,
0.25Jy<=S_1.4_<0.55Jy, and 0.2Jy<=S_1.4_<0.25Jy, respectively.
Table 3 gives the compilation of the radio, optical, and X-ray
data available for the sample sources.

Note (2): 1: the source belongs to Subsample 1 complete to S>=0.55Jy
in the sky area of 0.4414 sr
2: the source belongs to Subsample 2 complete with 0.25Jy<=S<0.55Jy
in the sky area of 0.0906 sr
3: the source belongs to Subsample 3 complete with 0.20Jy<=S<0.25Jy
in the area of 0.0550 sr
1,2: denotes sources with S>=0.25 Jy in the area of 0.0906 sr
2,3: denotes sources with 0.20Jy<=S<0.55Jy in the area of 0.0550 sr
Note (3): The slope is the derivative of a function y=a+bx+cx^2^ or
y=a+bx+d\c{dot}exp(+/-x).
If no function could be fitted to the spectral data (generally for
variable sources), a crude slope at 1.4 GHz is given
followed by u_SI=')'
Note (4): FRI: edge-darkened double
FRII: edge-brightened double
C: compact, unresolved with the VLA
C(1s): core-dominated compact with one-sided extended emission
C(2s): core-dominated compact with two-sided extended emission
cc: appended to the type denotes that a compact core has been
detected
CSS: compact steep-spectrum
Di: diffuse emission
Note (5): Code concerning the VLA maps available.
'1.4' and sometimes '4.9' indicate observing frequency, and
ABCP: VLA configuration used for observations
('P' means partially completed VLA in 1980).
* denotes that no map is available, and the source is represented
by fitted Gaussian components only.
If the VLBI-scale structure has been observed in a compact source,
this is indicated
Note (6): Optical type.
GAL : galaxy confirmed spectroscopically and/or with an extended image
(GAL) : possibly a galaxy
GAL? : identification ambiguous
QSO : quasar confirmed spectroscopically
BL : BL Lac object
RSO : red stellar object
NSO : neutral stellar object (most of them are quasar candidates)
BSO : blue stellar object (most of them are quasar candidates)
RO : red object too faint to be recognized as stellar or extended.
BO : blue object too faint to be recognized as stellar or extended.
EF : 'empty field' source, an identification likely beyond the
POSS limit.
'X' preceding the type indicates that an X-ray source coincides with
the radio position
Note (7): Two decimal digits precision indicate magnitudes measured with
photoelectric or CCD photometry
Note (8): For double source without a radio core, the given position
corresponds to a radio centroid
Note (9): References to VLA maps
