Nominal sonic heights are boom heights at crossbeam; actual sonic heights
are lower due to boom sag, but + 5cm for height of sonic above boom.
Good wind direction hours are determined from the medians of the
wind directions from the upper 9 sonics in each configuration.
Good direction hours are the sum of continuous periods of 20 minutes
or more with directions within ±30° of south.
Times in sixth column are start times for hot film data ingest if
different from column 3.
