Abstract:
    Maps of 212 extragalactic radio sources at 4.9 GHz are shown in Stokes
    I along with linear polarization vectors. The objects have a
    declination range of 0 degrees to -35 degrees and were chosen from the
    Hewitt & Burbidge quasar catalog with a spectral index less than -0.5
    and the NVSS survey with a minimum 1.4 GHz flux density greater than
    300 mJy. The observations were made with the Very Large Array in its B
    configuration, and the images have a typical resolution of 2
    arcseconds. One hundred ninety-five objects were resolved; 108 of the
    sources are quasars, and another 51 have been identified as galaxies.

Note (1): The catalog the objects was selected from. HB89 stands for
    Hewitt & Burbidge (1989ApJS..69..1H) quasar catalog and HB93 means
    that Hewitt & Burbidge did not include the quasar in their catalog
    until 1993 (Hewitt & Burbidge 1993ApJS..87..451H). NVSS denotes
    the Northern VLA Sky Survey (Condon+ 1998AJ..115..1693C).
Note (2):
    Q = quasar
    G = galaxy
    E = elliptical
    RG = radio galaxy
    A = AGN
    U = unidentified
Note (3):
    P = unresolved
    B = barely resolved
    L = lobe
    C = core
    J = jet
Note (4):
    a = from NED
    b = from this survey (4.8 GHz) and the NVSS (1.4 GHz)
    c = from HB93 (1993ApJS..87..451H)
Note (5): A denotes an Abell cluster. References and catalog
    abbreviations use the same convention as NED, except for QCC, which
    signifies that the quasar identification came from Quiniento et al.
    (1988A&AS...76...21Q). Asterisks indicate that a longer comment may be
    found in section 5 of the paper.
