Scientific paper

The global experiment GC030 was carried out in March 2008, during 48-hrs, with the European VLBI Network (EVN) and the Very Long Baseline Array (VLBA) recording at 512 Mbps in a geodetic-style dual-frequency S/X mode (2.3 and 8.4GHz). These VLBI observations were dedicated to imaging 105 weak extragalactic radio sources, with bright optical counterparts, detected during previous VLBI experiments (Bourda et al., 2010A&A...520A.113B).
The list of 105 target sources is detailed in this table, as well as the total flux densities as integrated from the X- and S-band images (units in mJy), the corresponding S/X-spectral index, the continuous structure index at X- and S-bands, and the parameters of the naturally weighted VLBI images at both bands. These latter are: (i) the restoring beam, which is an elliptical Gaussian with FWHM (Full Width at Half Maximum) major axis a and minor axis b (units in mas), with major axis in position angle phi (measured north through east; units in degrees); (ii) the peak brightness and the rms (root mean square) of the residuals of the final hybrid image (units in mJy/beam); (iii) the first contour level of the image (i.e. percentage of the peak and corresponding value in mJy/beam).
