3-meter-wavelength observations of the low-frequency-variable radio sources.
Abstract
The flux densities, angular dimensions of the scintillating components, and compactness indices were obtained for 117 objects from interplanetary scintillation observations of a sample of low-frequency variable radio sources. The meter-wavelength spectra are flat for most of the sources. The spectral indices and compactness parameter distributions are the same as for other AGN samples. The compactness indices do not correlate with low-frequency variable classes.
