The resulting light curves (of the flat-spectrum sources) are plotted in Figs. 2 to 23. For the May 1989 data the polarized flux density and the polarization angle are also given. As an example for the steep-spectrum sources (which were used to check for any instrumental effects and to correct those), see the source 1311+678 in Fig. 1 which was taken from the October 1992 observations at 6cm. Its modulation index was 0.44%.

For all total intensity light curves of the variable sources, structure functions were derived and plotted in Figs. 24 to 40.
