THE FIRST CALTECH-JODRELL BANK VLBI SURVEY .3. VLBI AND MERLIN OBSERVATIONS AT 5 GHZ AND VLA OBSERVATIONS AT 1.4 GHZ

We present the 5 GHz results from the first Caltech-Jodrell Bank (CJ1) VLBI survey. The 1.6 GHz maps were presented in two separate papers (Polatidis et al. 1995; Thakkar et al. 1995). These three papers complete the first stage of this program to map at both 1.6 and 5 GHz all objects accessible to Mark II VLBI in the complete sample of 135 objects with 1.3 > S-5GHz greater than or equal to 0.7 Jy, delta(1950) greater than or equal to 35 degrees, and \b\ > 10 degrees. The combination of the CJ1 sample with the Pearson-Readhead (PR) sample provides a complete, nux density-limited sample of 200 objects with S(5GHz)greater than or equal to 0.7 JY, delta(1950) greater than or equal to 35 degrees, and \b\ > 10 degrees for which all of the objects accessible to Mark II VLBI have been mapped at both 5 GHz (129 objects) and 1.6 GHz (132 objects). In addition to the 5 GHz VLBI maps, we present in this paper 5 GHz MERLIN observations of 20 objects and 1.4 GHz VLA observations of 92 objects in the combined CJ1 + PR sample. The VLA maps, together with L-band (1.3-1.7 GHz) maps available in the literature, provide a complete set of VLA maps for the combined CJ1 + PR sample. Finally, we present the radio spectra of the objects in the CJ1 sample. The combined CJ1 + PR VLBI surveys provide a sample which is large enough for a number of important astrophysical and cosmological studies. These will be presented in further papers in this series.
