Size comparison between VEGAS-SSS and ACS. Left panels: effective radii for objects common to the ACS and VEGAS-SSS catalogs (full sample with gray dots, reference sample with black circles). For each sample, the median ratio between the ACS and VEGAS-SSS R_h is reported, the rms_MAD and the number of sources used are given in parentheses. The histograms shown in the upper and right insets use the same color coding as the central panel and are normalized to 1 at peak value for the full sample. The effective radii from ACS data are used for the selection (unshaded area). The diagonal line represents the 1:1 relation. Right panels: as left panels, but the selection is based on R_h from VEGAS-SSS.
