Most of these observations were performed in total power and linear polarization. We give summary tables, light curves, and structure functions from these data sets. Due to the large number of individual observations, only examples of the lightcurves will be presented here; the complete set of figures will be accessible online**. Intraday variations are present in nearly all sources (detected during at least one of the observing campaigns). Variations in total flux density are usually accompanied by similar variability of the linear polarization. In most cases, the latter variations are stronger and faster by up to a factor of two. | Free Keywords: | galaxies : active, quasars : general, radio continuum : galaxies | Comment of the Author/Creator: | Date: 2003, APR | External Publication Status: | published | Document Type: | Article |
