20090720 report
CW/CCW inclinometry updated
20 July 2009
This inclinometry run was carried out on 18th July.
Datasets El Dirn HST mean leg temperatures Humidity
start start middle end %
(20090714 89 cw 05:00 6.6 6.5 6.9 5)
20090718 89 cw 08:15 5.5 6.0 6.7 55

The new data are recorded from the 3 active inclinometers and one of the
two strain gauge channels. The LT trace, which showed strange behaviour during the previous inclinometry run now shows no problems.

The differences between the (CW) model derived from this run and the previous run on 14th July are shown below.

-
The resulting rms scatters in the differences in (F1,F2,F3) for the left hand plot are (0.35", 0.48", 0.25") compared to (0.28", 0.27", 0.31") last time.
-
The
CW-CCW profile is normal, and is used to generate a hybrid track model
which was installed on the 20th July at 11:00.
- The strain gauge analysis suggest the loasing on the wheels continues to hold steady. (see strain gauge data).
