Abstract:
A complete sample of radio sources has been studied using the
interplanetary scintillation method. In total, 32 sources were
observed, with scintillations detected in 12 of them. The remaining
sources have upper limits for the flux densities of their compact
components. Integrated flux densities are estimated for 18 sources.
