The one dimensional point spread function for long exposure frames of the whole system atmosphere-instrument is deduced from solar limb observations using data recorded at Calern Observatory (France). It is then compared to the theoretical one deduced from the Von Karman model. Good agreement is found allowing to deduce the spatial coherence outer scale L0 and the Fried parameter r0. The found values obtained from data lie between 0.5 to 3 m for the outer scale and 0.5 to 1.5 cm for the Fried parameter.
