Abstract:
We have defined a complete sample of 228 southern radio sources at
408MHz with integrated flux densities S(408)>4.0Jy, Galactic latitude
|b|>10°, and declination -85°<δ←30°. The main
finding survey used was the Molonglo Reference Catalogue (Cat.
VIII/16). Sources in the sample were imaged at 843MHz with the
Molonglo Observatory Synthesis Telescope to obtain positions accurate
to about 1", as well as flux densities and angular sizes.

Note (1): Taken from the MRC, unless the source has more than one MRC entry,
in which case the name is from the original Parkes catalog (Bolton et
al. 1964, Cat. VIII/15; Price & Milne 1965, Cat. VIII/15) or
Parkes 2700MHz catalog (Bolton et al. 1979, Cat. VIII/15 and
references therein).
Note (2): Flag on Name, defined as follows:
d = The total angular extent is almost 10° (e.g. Cooper et al.
1965AuJPh..18..589C 1965AuJPh..18..589C ), whereas that of the inner lobes is 6.8' (Jones &
McAdam, 1992, Cat. J/ApJS/80/137). The position angle of the structure
varies at different angular scales: for the inner lobes it is 49°
(Jones & McAdam, 1992, Cat. J/ApJS/80/137).
e = The position, largest angular extent and position angle are the 408MHz
values from McAdam & Schilizzi (1977A&A....55...67M 1977A&A....55...67M).
f = The position is that of the core in the MOST image.
g = Angular size and position angle were measured from an ATCA contour map
(Norris et al. 1990PASAu...8..252N 1990PASAu...8..252N), as the MOST CUTS were affected by
MRC B2152-699.
Note (3): At 843MHz. The reference for the radio position is the same as
for S843MHz.
Note (4): See text for a discussion of the various telescopes used for the
flux densities measured at different frequencies.
Note (5): Flag on the flux density, defined as follows:
h = Flux density estimated from the radio spectrum.
i = Flux density not used in estimating S178MHz.
j = Variable at 843MHz (Gaensler & Hunstead 2000PASA...17...72G 2000PASA...17...72G).
Note (6): Defined in the sense Sν∝να.
Note (7): Flag on Sp+Index, defined as follows:
b = Spectral index defined between 408 and 5000MHz.
c = Spectral index defined between 843 and 5000MHz.
Note (8): The reference is the same as for the 843MHz flux density, except for
a few sources, noted in Section 5.1. We have imaged all sources with
LAS<35" with the ATCA at 5GHz (Burgess & Hunstead, 2000, Cat.
J/AJ/131/114), with the exception of MRC B0521-365, MRC B0743-673,
MRC B1740-517, MRC B1814-519, MRC B2153-699, and MRC B2259-375.
Note (9): Note on LAS, defined as follows:
d = separation of peaks of a double source;
e = largest separation of peaks of a complex source;
l = largest size of low-surface-brightness emission in a complex source:
the position angle given is that of the central axis;
m = deconvolved extent along the axis of a source, as in Jones & McAdam
(1992, Cat. J/ApJS/80/137).
Note (10): Defined in degrees east of north (modulo 90). The reference is the
same as for the 843MHz flux density, except for a few sources
which are noted in Section 5.1.
