Paper Abstract

We present the results of vertical profiles of refractive index structure constant Cn2(h) measurements made at the 1-m telescope, La Silla Observatory (ESO,Chile) using the generalized SCIDAR technique. Observations took place during July, August, November, 2002 and February 2003. The instrumentation, computer interface and a preliminary reduction software were provided by the Imperial College (London) scientific group. We describe the SCIDAR image processing technique and two inverting methods. The first, proposed by the Imperial College group, is based on the Tikhonov regularization and the second, on use at Nice University, is based on maximum entropy. Performances of both methods agree well. The profile integrals are compared to simultaneous DIMM seeing measurements made at La Silla Observatory.
