Activity highlights:
- array4.
- See profile note on 11th: diamond board problem, but staying up. crontab reset notes past 2 days
were erroneous because the command lacked complete path to script. Interrupts still occuring.
but adam was staying up. Some short looking files around the normal '12' hour restarts.
Will adjust Crontab to avoid extra restarts at 0:15,12:15.

Good wind direction:
array#4 (aug 9 20:00 - Aug14 08:00PDT) has 25.5 hours (6 unstable, 19.5 stable).

'p.ref' is measuring AHATS ref p with the 202BG connected between the
AHATS and CHATS references.
P.bedard now is the portable Paroscientific standard with reasonable resolution, but
low sampling rate connected to the Bedard pressure port now installed on boom 13b.unmigrated-wiki-markup

[Need to swap new 8P board with an old version 8M, but none available.\]
Heights of sensors are the same as array3.
Intended to move trh sensors, but tower/collars didn't work well for exact placement

-----------------------\-
Relatively large differences with east winds.
diag: ok, 6b spike in daytime ~13:00 occassionally (Birds, spiders?)
samples.sonic: ok
spd: ok, +/- 5 cm/s, with 12b,13b up to .5m higher, and 2b next in daytime with SWearly winds
dir: ok, new boom angles improved things at ~19z last night, but 1b, 10b still appear out.
w: ok, +/- .2 m/s, pitch looks better for some reason
tc: ok, +/- 0.3 deg, biases up to 1, some curious shift .3-.4 up/down from ~2-3:00 in 1b,2b,3b,4b
w'w': ok, +/- 0.01 m^2/s^2 (30 min avg for second moments)
u*: ok, +/- .1 m/s, some imaginary
sigma_w/u*:
