ISOPLANATIC ANGLE (θ0) TEMPORAL EVOLUTION

Temporal evolution of the isoplanatic angle integrated in [dome-20000]m between the sunset and the sunrise:
Astronomical dusk and dawn are shown too.
On the x-axis is time in UT (bottom), in MST (top). Mountain Standard Time MST=UT-7. Data points frequency is 2 minutes. Data points are re-sampled at a frequency of 20 minutes after a 1-hour moving average. The red error bars are the sigma over the 20 minutes sampling, computed before the moving average.
