| Title | | 'Some observing campaigns with Single Star SCIDAR' |
| Abstract | | Using the Single Star SCIDAR system and the Simulated Annealing technique, we have analysed observation data obtained during three observing campaigns. The experiment was performed with three different telescopes of diameters : 152-cm and 80-cm at the Observatoire de Haute Provence (OHP) and a 63-cm telescope at Observatoire de SIRENNE in France. We note that the simulated annealing technique is a new method to retrieve the atmospheric turbulence profile.
The data obtained are the spatio-temporal cross-correlations of a single star scintillation. Using the simulated annealing method we can obtain the profile of the integrated value of the refractive-index structure coefficient, the horizontal wind speed and the standard deviation of the horizontal wind speed fluctuations. From these profiles we can get the temporal evolution of the seeing, the isoplanatic angle, and the coherent time of wave-front. The temporal evolution is one profile every 11.2 s. It is also possible to have the telescope dome seeing.
