SEEING HORIZONTAL MAPS AVERAGES

Seeing 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 seeing in each pixel is obtained integrating the CN2 along the zenith and covering the temporal range [dusk,dawn]. The black iso-lines represent the heights of the Digital Elevation Model (DEM).
