Ratio of the integrated flux density to the peak pixel flux (S_int/S_peak; see Table A.3) plotted against the S/N of each of the CLASC sources for the April 26 (top) and April 11 (bottom) epochs. The red dotted lines represent the boundary between resolved (outside the red dotted lines) and unresolved (inside the red dotted lines) according to the criterion described above. Several CLASC IDs have been omitted for clarity.
