1995ApJS...99..297X THE FIRST CALTECH-JODRELL BANK VLBI SURVEY. III. VLBI AND MERLIN OBSERVATIONS AT 5 GHz AND VLA OBSERVATIONS AT 1.4 GHz W. XU, A. C. S. READHEAD, AND T. J. PEARSON Owens Valley Radio Observatory, California Institute of Technology, Pasadena, CA 91125 AND A. G. POLATIDIS AND P. N. WILKINSON University of Manchester, Nuffield Radio Astronomy laboratories, Jodrell Bank, Macclesfield, Cheshire SKI I 9DL, England, UK Received 1994 November 28; accepted 1995 January 26 ABSTRACT 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_5 GHz_ >= 0.7 Jy, {delta (1950) >= 35^deg^, and |b| > 10^deg^. The combination of the CJ1 sample with the Pearson-Readhead (PR) sample provides a complete, flux density-limited sample of 200 objects with S_5 GHz_ >= 0.7 Jy, {delta}(1950) >= 35^deg^, and |b| > 10^deg^ 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.
