Description:
Table 2 gives the 5 GHz high resolution radio source properties for
the 1861 Rosat-GreenBank (RGB) sources for which subarcsecond
positions and core radio flux densities were obtained.
After submission of this paper, we discovered a possible systematic
position error in a very small subset of sources. In particular, the
sources RGB J0131+005, RGB J0139+178, RGB J0143+129, RGB J0157+235A,
RGB J0232+202, RGB J0233+024A, RGB J0243+171, RGB J0256+035, RGB
J0303+059, RGB J0308+104, RGB J0312+243A, RGB J0312+242C, and RGB
J0314+063 were all observed in our "c" epoch VLA runs and show large
systematic offsets with respect to sources found in the NVSS survey.
We re-examined these sources and found the position reported in the
tables is accurate given our data, but that the noise on these fields
before any CLEANing is abnormally high. We thank Dr. Alastair Edge for
pointing out this discrepancy.
Table 3 gives the 5 GHz radio source properties for the 436
Rosat-Green Bank (RGB) sources for which only low resolution data were
obtained.
Table 4 gives the 83 Rosat-Green Bank (RGB) sources for which no radio
source greater than 5 sigma was observed in the follow-up VLA
observations. These catalogs consist of radio- and X-ray-loud AGN
selected from a correlation of the 1987 Green Bank radio catalog and
the Rosat All-Sky Survey.
