We are very grateful to the Franco-Armenian PICS and Jumelage for making our collaboration possible through financial support for three stays of E.N. in France. We gratefully thank Dario Fadda and Eric Slezak for giving us their wavelet analysis programmes, and Christophe Adami for performing a -model fit to our data. We also appreciated a discussion on radio sources with Jacques Roland. Last but not least, we thank the referee, Andrea Biviano, for several interesting criticisms and suggestions.
