WILKINSON University of Manchester, Nuffield Radio Astronomy Laboratories, Jodrell Bank, Macclesfield, Cheshire SK11 9DL, UK ABSTRACT We report lambda-18 cm VLBI observations made in 1991 September of a further 25 objects from the first Caltech-Jodrell Bank VLBI Survey (the CJ1 survey). The CJ1 sample is a complete, flux-density limited sample of 135 radio sources with total flux density at lambda-6 cm between 0.7 and 1.3 Jy. These observations complete the lambda-18 cm part of the survey. Together with the results of Paper I (Polatidis et al.), we have now observed 81 CJ1 sources at lambda-18 cm. Later papers in the series will present lambda-6 cm observations and the analysis and interpretation of the results.
