Abstract
The variation with direction of interstellar scattering at 81·5 MHz has been determined by two independent methods based on interplanetary scintillation measurements at 151·5 MHz, presented here, and at 81·5 MHz, already published. The scattering angle, which increases at low galactic latitudes, has a value of 0″·15 ± 0″·05 at 81·5MHz for the lines of sight perpendicular to the galactic plane. The effect of the scattering on the apparent angular diameters of OH and H2O maser sources is discussed.
