Table 3: The averaged total ux density values (S) and the variability measures: modulation indices ( S ) for
the sample of IDV sources. N - is the number of data points included in averages. The subscripts (1) and (2)
correspond to measurements for two dierent observing runs, (1) stands for May 1994 and (2) for August 1994.
The table shows the data for four frequencies: 8.6 GHz, 4.8 GHz, 2.4 GHz and 1.4 GHz.
