Sheila and Dan made this nice plot to show how the range degradation during  the lock the other night was well correlated with the wind going from 0 to 20 mph. This plot has the calibrated DARM spectrum, zoomed in two regions (10 mHz - 1 Hz) and (20 - 200 Hz), showing how the excess of noise in the low frequency region is up-converted in band. Here we had the "nominal no wind" 45 mHz blend for the ISI, as there was no wind when we left.
