Distances along the flux tubes for the background electron density derived from fitting the three radio bursts in this study. Also shown are three empirical density models multiplied by constant factors to intersect the densities derived from the bursts. The two radial distances deduced from 600 type III bursts by Dulk & Suzuki (1980) at the corresponding densities for 80 MHz and 43 MHz are shown as purple stars.
