VLBA observations are presented for 6 compact radio sources selected from the Peacock & Wall catalogue. From the new morphological and spectral information, 2 objects that in the Peacock and Wall catalogue are flat spectrum (α ≤ 0.5) sources, appear to be double sided objects with linear sizes of the order of one kpc. Three are core-jet sources and the last one is still an “enigmatic” object. These data complete the sample of small double compact sources in the Peacock & Wall catalogue and the complete list is given.

Abstract
VLBA observations are presented for 6 compact radio sources selected from the Peacock & Wall catalogue. From the new morphological and spectral information, 2 objects that in the Peacock and Wall catalogue are flat spectrum (α ≤ 0.5) sources, appear to be double sided objects with linear sizes of the order of one kpc. Three are core-jet sources and the last one is still an “enigmatic” object. These data complete the sample of small double compact sources in the Peacock & Wall catalogue and the complete list is given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
