Kellermann (1989) (D-array observations)
except where indicated in the text.

47- 54 F8.2 mJy PB4.86 []? 4.86-GHz peak brightness of the central
component in from the high-resolution
(VLA A-array) maps.
55 A1 --- n_PB4.86 A * symbol denotes a brightness which has been
derived from a brightness at 1.5GHz with
{alpha}= 0.7
57- 58 A2 --- Class [DPEQ? ] Radio-structure classification (1)
60- 64 F5.1 arcsec theta []? Angular size
--------------------------------------------------------------------------------
Note (1): Radio-structure classification
D denotes sources which are large radio sources, most of which are
double-lobed and have terminal hotspots on one or both sides of the nucleus
(the so-called "classical doubles" or "FR-IIs") but all of which are known
from lower resolution maps to have linear sizes much larger than a typical
galaxy size.
P denotes sources, other than those of class 'D', which have R>0.7
E denotes sources, other than those of class 'D', which have R<0.7
Q denotes sources, other than those of class 'E', which were undetected
in the D-array or the A-array observations, or which had very low fluxes
in D-array.
? symbol marks a classification which is subject to some reasonable doubt

resolution effects, converted to the Baars (1977) flux scale and, by use of a
spectral index of 0.7, converted from 178MHz to 151MHz.
