Scientific paper

We present the data of three observing campaigns with the VLA performed to study intraday variability in compact extragalactic radio sources. The first campaign (May 1989) lasted 5 days; total intensity as well as linear polarization data were obtained at 2, 3.6, 6, and 20 cm wavelength for 9 program sources. In the second observing run (February 1990), a five-antenna subarray of the VLA was used for 25 days to monitor the sources 0716+714, 0917+624, and 0954+658, with dense sampling at the same four wavelengths. In the third run (October 1992), which lasted 22 days, 8 program sources were monitored at 3.6, 6, and 20 cm wavelength, and 2 additional sources at 6 cm only, again with a five-antenna subarray. We present summary tables, light curves, and structure functions from these data sets.
