Measurements of stellar scintillation using photon counting statistics
Authors:B Stecklum
Abstract:The properties of the stellar scintillation were investigated using high speed photometry. The zenithal dependence of the total scintillation power turned out to be weaker than predicted by scintillation theory. The dependence of the total scintillation power on wavelength and the distribution of the intensity fluctuations according to a log-normal distribution agree with the theoretical predictions. The temporal behaviour of the stellar scintillation shows correlation time scales of less than 10 ms and some ten second which indicate the presence of the inner and outer scale of the atmospheric turbulence. The influence of other processes which cause intensity variations on the measurement of the total scintillation power was analyzed.
