Abstract
We present 5GHz high resolution VLA observations of 2,127 radio-- and
X-ray--emitting sources found in both the Green Bank (GB) 5GHz radio catalog
and the ROSAT All-Sky Survey (RASS). We report core flux densities and
positions accurate to =-0.5". Combined with the GB measurements
of the total radio emission, we derive the core-to-lobe ratio of objects in
our sample and discuss their core-dominance relative to samples of radio
galaxies and BL Lacertae objects. Our results show the RASS/Green Bank (RGB)
sample is approximately an order of magnitude more core-dominated than the
radio galaxy sample, but is more than an order of magnitude less
core-dominated than highly beamed BL Lacertae objects. Using simple beaming
models, this indicates the typical object in the RGB catalog exhibits moderately
beamed radio emission and is oriented at an angle to the line-of-sight
theta_RGB ~25^o - 35^o. The case of
the origin of the X-ray emission is not as clear; the data are consistent with
either an anisotropic unbeamed or moderately beamed X-ray component.
