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 (
) 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.
