20090923 report
CW/CCW inclinometry updated
23 September 2009
A routine inclinometry run was carried out this weekend with the following results.
Datasets El Dirn HST mean leg temperatures Humidity
start start middle end %
(20090912 89 cw 05:45 7.4 7.5 7.9 7
20090912 89 ccw 08:30 7.9 8.7 9.6 6)
20090920 89 cw 08:15 6.9 7.5 8.2 50
20090920 89 ccw 11:00 8.2 9.6 10.5 40
The new data are recorded from the 3 active inclinometers and one of the
two strain gauge channels. all channels look normal.
-
The differences between the (CW) model derived from this run and the previous run on 12th September are shown below.

-
The resulting rms scatters in the differences in (F1,F2,F3) are (0.38", 0.23", 0.24") compared to (0.45", 0.67", 0.26") last time.
-
The
CW-CCW profile is normal, and is used to generate a hybrid track model
which was installed on the 20th September at 16:30.
- The relative loadings on the wheels remains extremely stable (see strain gauge data).
