20090817 report
CW/CCW inclinometry updated
17 August 2009
This inclinometry run was carried out on 15th August.

20090801 89 ccw 09:30 7.1 7.8 8.6 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 continues to show no problems.

The differences between the (CW) model derived from this run and the previous run on 1st August are shown below.

-
The resulting rms scatters in the differences in (F1,F2,F3) are (0.34", 0.38", 0.30") compared to (0.31", 0.25", 0.36") last time.
-
The
CW-CCW profile is normal, and is used to generate a hybrid track model
which was installed on the 16th August at 11:30.
- The strain gauge analysis suggest the loading on the wheels continues to hold steady (see strain gauge data).
