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:-
TOTAL WAVEFRONT COHERENCE TIME (τ0,TOT) - [dome-20000]m
BOUNDARY LAYER WAVEFRONT COHERENCE TIME (τ0,BL) - [dome-600]m
FREE ATMOSPHERE WAVEFRONT COHERENCE TIME (τ0,FA) - [600-20000]m
- 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).
