Measured cumulative fluxes as a function of radial separation from the center of the maps. The top-left panel presents the results of radial profiles for CHVC 070+51-150, the top-right panel for CHVC 108-21-390, and the bottom panel for CHVC 162+03-186. The blue line represents the measured fluxes for the combination, the green line the values for WSRT, and the red line Effelsberg. The dashed line marks the HPBW of the WSRT. In all three cases the measured flux after the combination is in good agreement with the measured value from the single-dish data. In the case of CHVC  070+51, about 20% more flux has been detected by the single-dish than by the radio interferometer. The difference between the combined and interferometric data is 40% for CHVC 108-21-390. For CHVC 162+03-186, the ratio of interferometric/combined accounts for almost 50%. This is the largest measured ratio for the three CHVCs. It also reveals that a large portion of the cloud consists of WNM which is traced best by the single-dish. The results demonstrate that the combination achieves the expectations.
