2000A&AS..145....1P Long-term monitoring of selected radio sources. PENG B., KRAUS A., KRICHBAUM T.P., WITZEL A. Received January 27; accepted March 21, 2000 Abstract: The Effelsberg 100 m radio telescope has been used, over a period of 5.5 years, to monitor the flux densities of 40 extragalactic radio sources, including the complete sample of 13 flat spectrum sources from the S5 Survey, and various other active sources. The study of their long-term variability characteristics at several wavelengths, the source light curves, spectra, and a statistical analysis are presented and discussed in this paper. Key words: galaxies: active - BL Lacertae objects: general - quasars: general - radio continuum: galaxies
