Parameter values for the best fit models as defined by Eq. (2).
|Outer area (linear model)||Inner area (cubic model)|
|Data set||a||σ a||b||σ b||a||σ a||b||σ b||c||σ c||x 0||σ x 0|
Notes. The results are reported for the on-sky data sets (see Fig. 6) as well as for the data sets simulated with the same tip-tilt sampling (see Fig. 7). The ideal model corresponds to the result of the fit performed on the simulated model shown in Fig. 3, including a much larger number of simulated data points (not biased by the sampling or by the offset in the orthogonal direction of the applied tip/tilt). Values below 10-3 are considered insignificant and marked as 0.
