\caption{\label{tab:Tab1}Estimates of the minimum flux density detectable at $X$ and $S$-bands for the baselines used for EC025A and EC025B (Eb~=~Effelsberg, Mc~=~Medicina, Nt~=~Noto, On~=~Onsala, Ro~=~Robledo), for geodetic-style, dual-frequency $S/X$~observations recorded at~1~Gb/s during 5-min long scans. A radio source is considered detected if the ${\it SNR }\geq 7$.}
