AbstractThroughout the quiet-Sun years 1982–1987, the Clark Lake Radioheliograph mapped the solar corona on a daily basis at frequencies from 30 to 100 MHz. The Clark Lake maps show a variety of features which we have analyzed quantitatively. Among the features are coronal streamers, which appear to cross the solar disk during a solar rotation. We have modeled the streamers with various geometrics and density profiles, and computed ray-tracing images for comparison with the CLRO maps. These models produced estimates of density and spatial scales in 3 dimensions for the streamers. We discuss the significance of these estimates and compare them with inferences made from optical observations. One of the possible conclusions we draw from these comparisons is that there are unresolved structures in stremers, not observable optically in the limb data.
