High-resolution observations of radio sources with 0.6 < z≤ 1.0
High-resolution, high-sensitivity 8.4- and 5-GHz VLA observations and 5-GHz MERLIN observations are presented for 32 FRII radio sources with 0.6 < z≤ 1.0 from the 3CRR sample. These data conclude a long-term project in which high-sensitivity, high-resolution observations of a complete sample of 97 FRII quasars and radio galaxies with z≤ 1.0 have been collected; data for sources with z≤ 0.6 from this sample have been presented previously in a series of papers. Jet features are detected in 16 of the 32 new sources, giving a jet detection rate of 50 per cent in this high-redshift subsample. Jet and hotspot detectability in the subsample are discussed.
