For my own sanity, I try here to document all the heights so far:

*3/18/09, TWH added the height of the sonic measurement volume above the top of the boom (5.5? cm).

**Note that the 7m sonic was moved up "about 4-5 cm" on Aug 3 at 09:41 (see logbook entry)

 "-" means shouldn't have changed from last

"x" means value not needed

TRH at "5m" and "4m" were moved between array 2 and array 3, but measured during array 4.

final values to be used in bold

ref4 was 0.040m above ref3, but for the profiles, the reference was the top of the lowest sonic boom, which was 0.027m below ref3.
