where lean and leanaz were determined with the planar fit technique and recorded in the sonic cal files. The boom-length is the distance from the base of the boom to the sonic measurement volume = 1.765 cm.
In the following tables, a positive height difference indicates that the sonic is higher than the base of the boom. The height differences are in cm. The Date/time in the first column is when the new height difference takes effect.
