THE REVISED GB GB2 SAMPLE OF EXTRAGALACTIC RADIO-SOURCES/

This paper presents the revised sample of 373 extragalactic radio sour ces brighter than 0.2 Jy at 1.4 GHz. These sources, selected from the finding Green Bank surveys, were mapped at 1465 MHz using the VLA at d ifferent configurations. The biases introduced into the original GB an d GB2 catalogues by confusion as well as partial resolution by the VLA at A-configuration, are eliminated. In effect! a number of sources ha ve 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 greater than or equal to 0.55 Jy, 0.25 Jy less than or equ al to S-1.4 < 0.55 Jy, and 0.2 Jy less than or similar to S-1.4 < 0.25 Jy, respectively. A compilation of the radio, optical, and X-ray data available for the sample sources are presented in Table 3. New 4.9-GH z VLA images of selected sources are included. A number of statistics describing radio morphological and spectral contents of the sample, ra dio variability, revised source counts, redshift distributions, etc. a re given.
