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.
