Abstract

A comparison of isoplanatic angles derived from balloon- borne in-situ measurements of the index of refraction structure constant profiles and remote optical measurements of stellar intensity fluctuations using an isoplanometer is shown. Concurrent data taken over a six day period in the spring of 1986 show reasonably good agreement between the methods considering normal atmospheric variability. Possible reasons for differences between individual measurements are discussed.
