Abstract
We report further results from our imaging survey at 15 GHz (λ = 2 cm) with the Very Long Baseline Array (VLBA). 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 with those derived from total intensity variations at 22 and 37 GHz. These are consistent with intrinsic brightness temperatures in the range 10^(10)–10(12) 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 ± 0.0004 for 1155+251.
