We thank Dr. Patricia Reich of the Max-Planck-Institut für Radioastronomie (MPIfR) for providing maps of the G.C. region at 408, 45 and 34.5 MHz processed in different ways, and for critically reading an early version of the manuscript. We also thank Prof. Richard Wielebinski, Director of the MPIfR for making available the computing facilities of his institution. The help in many ways of Fernando Olmos was invaluable.
