For entries from the first catalog, this is the local rms noise estimate at the source position, and does not include any additional error for spatially extended sources.. Interferometric responses (fringes) were obtained for all types of studied radio.

First fringes for the radioastron project were already detected using the effelsberg 100 m telescope and the asc correlator in 2011 and presented in an earlier press release.. Radioastron works together with earth based radio telescopes to give interferometer baselines extending up to 350,000 km, more.
