Dome-seeing subtraction from G-SCIDAR measurements

摘要

We have developed an algorithm to eliminate the dome seeing contribution to turbulence profiles derived from G-SCIDAR data. The algorithm, based on the parity of functions, is completely automated and it takes only a few seconds to process a full night of G-SCIDAR data. Seeing measurements obtained from turbulence profiles derived from G-SCIDAR observations and removing the dome contribution with our algorithm are in good agreement with seeing data obtained using Differential Image Motion Monitors (DIMMs). An important advantage of the proposed procedure is that it permits an automated reduction during the calculation process and it could be implemented to work in real time. The formulation to identify the shape of the dome seeing could be extended to other problems of shape recognition whenever it is even.
