Sighting along the PAM masts, the orientation of the upwind array is 39.6 221 deg and the downwind array is 39.2 40 deg.  Adding 90 and 270 degrees and the declination (13.7 deg) gives 323324.3 7 degrees true for the upwind array and 322323.9 7 deg true for the downwind array, which is are close to the design value of 325 deg.  Note that the datascope had the wrong declination (but don't know what value was used for the site survey), 13.4 degrees rather than  13.7 degrees, which may account for 0.3 degrees of the differences of 1.7 and 2.1 degrees.  

Note that the tripods for the second upwind array are already set up roughly N of the profile tower.  The data scope gives an angle of 156 deg magnetic from the leg of  the SW tripod to the profile sonics, so the profile winds from directions greater than 156+180 + 13.7 = 349.7 deg true should be used with caution.
