Tables list three independent measurements of sonic azimuth. I measured each row at different times, requiring independent estimates of proper alignment of datascope relative to sonic, which is the biggest source of uncertainty. I found that the sun angle is much better for visibility of the sonics at 7 am than at 10 am, so I reshot the azimuths done prior to 7/11/08.
The cal_file row is the value used for the sonic azimuth in the cal file in order to give winds in a coordinate system with the sonic u component normal to the array: use + 13.7 - (325-180) = use - 131.7
