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.
