- Abstract
We report further results from our imaging survey at 15 GHz (lambda=2cm)
with the Very Long Baseline
Array. This paper presents single epoch images for 39 sources,
bringing the total number of objects in the sample to 171. Our sample is
representative of a complete unbiased sample and it
will be used for statistical
analysis of source properties. We compare the observed brightness
temperatures derived from our VLBA observations to those
derived from total intensity variations at 22 and 37 GHz. These
are consistent with intrinsic brightness temperatures in the range
1010 to 1012 K.
We also present three new spectroscopic redshift values:
z=0.517+/-0.001 for 0026+346,
z=1.591+/-0.003 for 0727-115,
and z=0.2016+/-0.0002 for 1155+251.
Images from this VLBA 2 cm survey are available on
