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:

TOTAL SEEING (ε_TOT) - [dome-20000]m
BOUNDARY LAYER SEEING (ε_BL) - [dome-600]m
FREE ATMOSPHERE SEEING (ε_FA) - [600-20000]m

The seeing in each pixel is obtained integrating the C_N² along the zenith and covering the temporal range [dusk,dawn]. The black iso-lines represent the heights of the Digital Elevation Model (DEM).

ε_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).
