WAVEFRONT COHERENCE TIME (τ0) MAPS AVERAGES

Wavefront coherence time horizontal map extended on a 50km x 50km square centred on LBT (represented with a black dot). The seeing is integrated over three different vertical slabs:
The wavefront coherence time in each pixel is obtained integrating the CN2 and wind speed along the zenith and covering the temporal range [dusk,dawn]. The black iso-lines represent the heights of the Digital Elevation Model (DEM).



  • τ0,TOT AVERAGES:
    Averages are computed over the whole night [<dusk> - <dawn>]UT and also in the first, central and last part of the night (see partition).
