Abstract

A 10-11 cm aperture stellar scintillometer can measure atmospheric isoplanatic angles reliably provided the normalized variance and the zenith angle of the data are sufficiently, restricted. Within these constraints, the normalized variance data has a zenith angle power law that is quite close to the theoretical prediction. This is a self-consistent indication that the instrument is actually measuring the isoplanatic angle.
