Description:
    A sample of 98 Compact Steep-Spectrum and GHz-Peaked Spectrum
    (CSS-GPS) candidates from the B3-VLA sample has been observed with the
    VLA (A configuration) at 8.5, 4.9 and 1.5 GHz, with resolutions of
    0.2, 0.4 and 1.4 arcsec, in total intensity and polarization. Source
    positions, flux densities, polarization parameters, angular sizes and
    spectral information are reported for the confirmed CSS (Table 3) and
    the non-CSS (Table 3bis) sources.

Note (1): The symbols are:
   ~ = diffuse of extended objects, position not accurate
   b = bridge,
   j = jet
   t = tail (NW)
   W = W plume
   N,S = North/South tail

Note (2): The symbols are:
   * = indicates that the total intensity or polarization or spectral index
       of several contiguous components is listed. The same value is
       repeated in all the involved lines
   @ = it was not possible to separate the two components in the
       polarization image.
