Radio Source Counts

In this webpage you can find a tabulation of observed Euclidean normalized differential radio source counts
at various radio frequencies including, when relevant, an estimate of the clustering contribution to the errors.
The present tables have been published in the review
Radio and millimeter continuum surveys and their astrophysical implications
by de Zotti G., Massardi M., Negrello M., Wall J..
We also list the estimates of the Euclidean normalized differential radio source counts
for frequencies smaller than 5 GHz obtained with the evolution model for AGNs presented in
A model for the cosmological evolution of low frequency radio sources
by Massardi M., Bonaldi A., Negrello M., Ricciardi S., Raccanelli A., de Zotti G.
We gratefully appreciate acknowledgements to the use of the tables below by citing any of the papers mentioned above.
