INSTRUMENTATION FOR A STUDY OF RANDOM ASTRONOMICAL REFRACTION.

Abstract

The report presents a description of the instrumentation system developed for the acquisition of data for a study of short period variations of astronomical refraction. The optical system used for the stellar observations, the comparator for the measurement of the stellar images and the meteorological instrumentation for the determination of the atmospheric parameters are discussed in detail.
